For a small company just starting, which baseline security products (AV, firewall, email security) are must-have vs optional?

Starting a small company means every dollar and every hour counts. Setting up the right security perimeter on day one prevents catastrophic data breaches, while avoiding "security bloat" keeps your overhead manageable.

Here is the breakdown of what is a must-have versus what is optional (or can be deferred) for your baseline security stack:

Must-Have Baseline Security (Do Not Skip)

• Next-Gen Antivirus / Endpoint Detection & Response (NGAV/EDR)
  • Why it’s a must-have: Traditional signature-based antivirus is dead. Modern EDR (like Microsoft Defender for Endpoint, CrowdStrike, or SentinelOne) actively monitors behavioral anomalies, blocks ransomware, and allows you to isolate a compromised laptop remotely.
  • Priority: Critical. Every single company-owned device (laptop, desktop, phone) needs this on day one.
• Cloud Email Security & Phishing Protection
  • Why it’s a must-have: Over 90% of cyberattacks start with a phishing email or compromised credentials. Standard Microsoft 365 or Google Workspace filters catch a lot, but a dedicated layer (such as Abnormal Security, Avanan, or built-in advanced protection tiers) is required to stop spear-phishing, business email compromise (BEC), and malicious links.
  • Priority: Critical. If your email goes down or gets spoofed, your business halts.
• Identity & Access Management (IAM) with Multi-Factor Authentication (MFA)
  • Why it’s a must-have: While not explicitly a "firewall," MFA is the modern perimeter firewall. Enforcing phishing-resistant MFA (authenticator apps or hardware keys, avoiding SMS if possible) across all accounts—especially email, cloud storage, and payroll—stops credential stuffing dead in its tracks.
  • Priority: Critical. Implement via your identity provider (e.g., Microsoft Entra ID or Google Workspace Admin).

Optional or Deferred Security (Nice-to-Have for Later)

• Traditional Hardware Firewalls
  • Why it’s optional: If your team works remotely or uses a cloud-first infrastructure (SaaS tools, cloud servers), a physical office firewall (like a Meraki or Fortinet box) is largely redundant. Your local router's stateful inspection combined with device-level firewalls built into Windows/macOS is usually enough.
  • When to get it: Only if you have a physical brick-and-mortar office with local servers, physical network storage (NAS), or wired local devices.
• Data Loss Prevention (DLP) Suites
  • Why it’s optional: Advanced DLP prevents employees from emailing credit card numbers or proprietary source code out of the organization. For a 5-person startup, this is massive overkill and administrative noise; basic policies combined with a culture of trust work better initially.
  • When to get it: When you scale past 25–50 employees or handle strict regulatory data (HIPAA, PCI-DSS).
• Security Information and Event Management (SIEM) / 24/7 SOC
  • Why it’s optional: Aggregating all logs into a massive SIEM and paying for a 24/7 Security Operations Center is financially prohibitive and unnecessary for a startup with minimal attack surface.
  • When to get it: When enterprise clients demand SOC 2 compliance or you have dedicated IT/Security staff to triage the alerts.

If you'd like, let me know:

• How many employees you are starting with
• Whether your team is fully remote or in an office
• What cloud ecosystem you are using (Microsoft 365 vs. Google Workspace)

I can help you tailor specific product recommendations and budget-friendly license tiers.

For a small company, I’d keep the baseline simple and layered rather than buying a stack of enterprise security products. NIST’s current small-business guidance emphasizes MFA, patching, backups, updated antivirus, phishing protection, and employee training as foundational controls.

Must-have

What is not necessarily a separate product

A common mistake is thinking you need to buy three separate appliances/services for AV, firewall, and email.

For example, if you're using a mainstream business cloud suite, much of the email/identity/endpoint security may already be available in the platform. The important question is whether the security features are actually configured and monitored, not whether you've purchased another security logo.

Optional / add when you have the need

• Dedicated EDR/XDR — worthwhile once you have enough endpoints or sensitive data that centralized detection/response matters. For a 5-person startup, a well-managed endpoint protection product may be sufficient initially.
• Dedicated email security gateway — useful for higher-risk organizations, but often unnecessary for a very small company if the native cloud email protections are configured properly.
• Enterprise firewall/UTM appliance — worthwhile if you have an office with servers, lots of devices, guest networks, VoIP, IoT, etc. Less important for a completely cloud-based/remote workforce.
• MDM/UEM — increasingly valuable once employees use company laptops and especially phones/tablets.
• Vulnerability scanning — useful as infrastructure becomes more complex.
• SIEM/SOC/MDR — generally overkill for a tiny company unless you have regulatory requirements, valuable intellectual property, or significant risk. Managed detection and response can become attractive before building an internal SOC.
• DLP — useful when you handle substantial confidential customer data, intellectual property, financial information, or regulated data.
• Network IDS/IPS — generally a later-stage control for a small, cloud-first business.

CISA likewise treats email/web protections and firewalls as important defensive layers, while more sophisticated monitoring such as EDR, DLP, IDS/IPS and SIEM represents a broader detection capability.

If I had a $0–$5k security budget

I'd spend it roughly in this order:

1. Business email + identity with MFA
2. Endpoint protection/EDR
3. Reliable backup
4. Secure router/firewall + Wi-Fi
5. Password manager
6. Device management/patching
7. Security awareness/phishing training
8. MDR/managed security if nobody internally can monitor alerts

The key point: MFA + patching + backups + endpoint protection + secure email usually give a tiny company considerably more protection than buying an expensive firewall and leaving everything else poorly configured.

NIST's 2026 draft guidance specifically recognizes that very small businesses have different needs from larger enterprises and recommends scaling cybersecurity measures according to the organization's size, IT complexity, resources, and regulatory/contractual requirements.

If you tell me roughly how many employees/endpoints you have, whether everyone is remote or there's an office, and whether you're on Microsoft 365 or Google Workspace, I can turn this into a concrete “buy these 5 things / skip these 10 things” startup security stack.

For a small company just starting, the goal is not to buy every security product — it is to cover the most common failure points: stolen credentials, phishing, malware/ransomware, lost devices, and weak access controls. Guidance from NIST and the FTC emphasizes basics like MFA, endpoint protection, patching, backups, and secure email practices as foundational controls.

A practical baseline:

NIST Computer Security Resource Center Federal Trade Commission## Minimum viable security stack (1–25 employees)

A reasonable starter stack:

1. Endpoint security — Must-have

Buy:

• Business antivirus/EDR for every company device
• Central management console
• Automatic updates and alerts

Avoid relying only on:

• Built-in consumer antivirus
• “We’ll install it if someone gets infected”

Why: endpoints are a common entry point for attackers, especially through email attachments, stolen credentials, and browser exploits.

---

2. Email security — Must-have

Buy/use:

• Business email service (rather than personal email accounts)
• MFA
• Spam/phishing filtering
• SPF, DKIM, and DMARC configured for your domain

For many small companies, email is the highest-risk system because phishing attacks target employees directly.

---

3. Firewall — Must-have in some environments

Small remote-first company:

• A cloud-first setup may make a dedicated firewall less urgent.

Office with local network:

• Business firewall/router is a baseline requirement.

Look for:

• Automatic firmware updates
• Separate guest Wi-Fi
• VPN support
• Basic intrusion prevention features

---

Optional at startup (add as you grow)

---

A sensible priority order if budget is tight

1. ✅ MFA everywhere
2. ✅ Business email security + SPF/DKIM/DMARC
3. ✅ Endpoint EDR/AV
4. ✅ Backups with restore testing
5. ✅ Password manager
6. ✅ Business firewall (if you have an office network)
7. ➕ Advanced monitoring/compliance tools later

A common mistake for startups is spending heavily on a firewall while leaving email, identity, and endpoints weak. For most small businesses, identity + email + endpoint protection provide the biggest risk reduction per dollar.

If you share your company size, whether employees are remote or office-based, and what you handle (customer data, payments, healthcare, etc.), I can suggest a more specific starter stack.

Starting a small company is an absolute whirlwind, and cybersecurity can easily feel like a massive, expensive distraction. However, a single breach can shutter a young business before it even finds its footing.

Here is the breakdown of what is an absolute must-have on day one versus what is optional (or can be deferred as you scale).

Must-Have Baseline Security Products (Day One)

• Next-Generation Antivirus / Endpoint Detection and Response (NGAV / EDR)
  • Why it's a must-have: Traditional signature-based antivirus is dead. Modern EDR solutions (like Microsoft Defender for Business, CrowdStrike Falcon, or SentinelOne) actively monitor behavior, stop ransomware in its tracks, and allow you to isolate an infected laptop remotely. Every single company-owned laptop or desktop needs this immediately.
• Cloud Email Security
  • Why it's a must-have: Phishing, business email compromise (BEC), and malicious attachments are how the vast majority of small business attacks start. If you are on Google Workspace or Microsoft 365, their default filters are a good baseline, but adding a specialized layer (like Avanan, Abnormal Security, or Cloudflare Email Security) to catch sophisticated credential harvesting is critical.
• Business-Grade Firewall / Router
  • Why it's a must-have: If you have a physical office or remote employees connecting via a company VPN, you need a stateful inspection firewall (such as Fortinet, SonicWall, or Ubiquiti UniFi). It secures your perimeter, handles secure remote access, and blocks inbound network scanning attempts. If your team is 100% remote working out of coffee shops and homes, your "firewall" shifts entirely to endpoint controls and secure cloud gateways.
• Identity and Access Management (IAM) & Multi-Factor Authentication (MFA)
  • Why it's a must-have: While not strictly an "appliance" like an AV or firewall, enforcing phishing-resistant MFA (via Okta, Duo, or built-in Microsoft/Google authenticators) across every single SaaS tool, email account, and workstation is the single highest-return security control you can implement.

Optional / Deferred Security Products (Scale As You Grow)

• Dedicated Security Information and Event Management (SIEM) / SOC-as-a-Service
  • Why it's optional: For a 5-person startup, paying for a 24/7 Security Operations Center or a heavy SIEM tool is overkill and budget-prohibitive. Rely instead on the built-in alerting dashboards of your EDR and email security tools. Look at a SIEM only when compliance mandates it or when you cross roughly 50+ employees.
• Data Loss Prevention (DLP) Software
  • Why it's optional: Advanced DLP tools prevent employees from accidentally leaking source code, financial records, or customer PII. In a tiny, tight-knit founding team, heavy-handed DLP is rarely necessary. You can achieve 90% of this risk reduction by enforcing basic cloud storage access rules (e.g., proper Google Drive/SharePoint permissions).
• Web Application Firewalls (WAF) / Advanced DDoS Protection
  • Why it's optional: Only applicable if your startup is building and hosting its own web application or SaaS product from scratch. If you are just a standard business using off-the-shelf SaaS tools (Slack, QuickBooks, Zoom), you don't need this. If you do host an app, rely on edge platforms like Cloudflare or AWS Shield for baseline protection rather than building it yourself.
• Vulnerability Scanners / External Attack Surface Management
  • Why it's optional: Automated daily scans of your external IP space or codebases are great, but for a new company, a quarterly manual review of who has access to what is usually sufficient. Invest here only once you have public-facing web infrastructure or formal enterprise client audits (like SOC 2) on the horizon.

To help tailor this to your exact setup, tell me:

• Are you operating fully remote or do you have a physical office?
• What cloud ecosystem are you primarily using (Google Workspace, Microsoft 365, or a mix)?
• Roughly how many employees are starting on day one?

For a small company, I’d avoid buying a huge security stack on day one. The goal is strong baseline controls with minimal management overhead. NIST’s current small-business guidance emphasizes MFA, patching, updated antivirus, backups, and strong authentication as foundational controls.

My baseline

If money is tight

I'd spend in roughly this order:

1. MFA → 2. managed endpoint protection → 3. secure email → 4. patching/MDM → 5. backups → 6. firewall → 7. password manager → 8. training → 9. advanced monitoring.

One important nuance: "firewall" doesn't necessarily mean buying an expensive next-generation firewall appliance. If you're primarily using cloud applications and have a small office, a good business router/firewall plus properly secured endpoints can be perfectly reasonable.

Likewise, don't buy a separate email-security product simply because the category exists. First configure the controls already included with your email provider. CISA specifically encourages small businesses to use well-maintained cloud services rather than taking on the burden of securing on-premises email infrastructure.

The minimum viable stack I'd actually deploy

For a typical 10-person startup:

• Microsoft 365 or Google Workspace with MFA and built-in phishing/spam protection
• Managed EDR/AV on every endpoint
• Business firewall/router
• MDM for company devices
• Password manager
• Automated cloud/offline backups
• SPF + DKIM + DMARC
• Automatic OS/application patching
• Basic security awareness training

That gives you a much better baseline than spending the same budget on a fancy firewall while leaving accounts, endpoints, or backups poorly protected.

The big takeaway is that AV + firewall + email security alone is no longer a sufficient baseline. Identity protection—particularly MFA—has become equally important; CISA calls MFA one of the simplest and most effective ways for SMBs to reduce account compromise.

For a brand-new, small company, setting up cybersecurity can feel overwhelming. To maximize protection on a lean budget, here is how the baseline security products break down into must-have versus optional essentials.

Must-Have Security Products (Non-Negotiable)

• Endpoint Protection / Next-Gen Antivirus (EDR/NGAV) : Traditional antivirus isn't enough anymore. You need a modern endpoint solution (like CrowdStrike Falcon, Microsoft Defender for Business, or SentinelOne) that offers behavioral monitoring and Endpoint Detection and Response (EDR) . Since remote and office laptops are your perimeter, protecting every device is priority number one.
• Email Security & Anti-Phishing : Over 90% of cyberattacks start with an email. Relying solely on default Microsoft 365 or Google Workspace filters leaves gaps. A dedicated cloud email security layer (like Abnormal Security, Avanan, or Proofpoint Essentials) to block credential harvesting, spear-phishing, and malware is a must-have from day one.
• Cloud-Managed Firewall / Secure Router : If you have a physical office or remote workers accessing a local network, a business-grade firewall (such as Fortinet, Meraki, or Ubiquiti UniFi) is essential. If you are a 100% remote company with zero physical office, your reliance shifts entirely to device firewalls and secure cloud access, making a physical hardware firewall optional—but network boundary defense remains vital.
• Identity and Access Management (IAM) / Multi-Factor Authentication (MFA) : Though not strictly an "app" in the traditional AV/firewall sense, MFA enforced across all accounts (email, cloud storage, accounting software) is the single highest-return security control you can implement.

Optional or Secondary Security Products (Can Wait)

• Data Loss Prevention (DLP) Tools : Advanced DLP software monitors and blocks sensitive data (like credit cards or SSNs) from leaving the organization. For a startup, basic cloud-storage sharing restrictions (e.g., restricting public links in Google Drive or OneDrive) are sufficient until you scale or handle regulated data (like HIPAA/PCI).
• Security Information and Event Management (SIEM) : SIEM tools aggregate logs from every server, device, and application for real-time analysis. This is overkill and too expensive for a tiny startup unless mandated by a specific enterprise client or compliance framework.
• Dedicated Vulnerability Scanners : While scanning your external IP addresses or cloud infrastructure for missing patches is important, modern endpoint agents and cloud posture management tools often handle the basics. A standalone enterprise vulnerability scanner can wait until your IT infrastructure grows more complex.
• Advanced Employee Security Awareness Platforms : While basic security awareness training is important, rolling out automated, continuous phishing simulations and extensive training platforms (like KnowBe4) can be deferred for the first few months in favor of a 30-minute live onboarding talk on spotting scams.

If you'd like, let me know:

• Your industry (e.g., healthcare, fintech, e-commerce)
• Whether your team is fully remote or in an office
• What cloud productivity suite you use (Microsoft 365 or Google Workspace)

I can tailor a specific budget-friendly product stack for your exact setup.

For a small company starting from scratch, I’d keep the baseline simple and layered. The biggest mistake is buying lots of security products while leaving MFA, patching, backups, and account controls weak.

Must-have baseline

The SBA specifically recommends antivirus on business computers, firewalls for network protection, automatic software updates, and MFA. www.sba.govwww.ftc.gov NIST likewise puts MFA, access control, training, patching, and backups near the foundation of an SMB security program.

What about the three products you mentioned?

1. AV/EDR — Must-have

Don't think of this as the old-school "antivirus" that just scans for viruses. For a new company, I'd prefer a managed EDR/NGAV product that provides behavioral detection, isolation, and centralized management.

If you're using Windows, don't necessarily assume you need an expensive third-party AV—Microsoft's built-in endpoint security can be a reasonable starting point depending on your Microsoft licensing and risk profile. The important thing is that every endpoint is protected and centrally managed.

2. Firewall — Must-have, but don't overbuy

You need a properly configured firewall at the office/network boundary. A small 5–20 person company generally doesn't need an elaborate enterprise firewall stack.

If you're primarily SaaS/cloud-based and employees work remotely, the firewall becomes less important than endpoint security + identity/MFA + secure remote access. Don't spend $10k on a firewall while leaving employee Microsoft/Google accounts protected only by passwords.

3. Email security — Must-have, but start with your email provider

Phishing and business-email compromise are enormous risks for small businesses.

But you don't necessarily need a separate email-security appliance/service on day one. If you're on Microsoft 365 or Google Workspace, start with their native protections and configure them properly.

At minimum, configure:

• SPF
• DKIM
• DMARC
• MFA
• Anti-phishing/anti-spam policies
• External-email warnings where appropriate
• Good admin-account controls

The FTC specifically recommends SPF, DKIM, and DMARC for businesses using their own domains.

Usually optional at the beginning

I'd defer these until the company/risk profile warrants them:

• Dedicated email security gateway — useful when phishing volume/risk is high or you need advanced controls.
• SIEM — usually overkill for a tiny company unless required by customers/regulators.
• SOC/MDR — valuable if you don't have IT/security expertise, but not necessarily a "product" you need immediately.
• DLP — becomes more valuable when you're handling substantial confidential/customer data.
• Vulnerability scanner — useful, but basic patch management comes first.
• Network IDS/IPS — nice to have; many modern firewalls include this functionality.
• Zero Trust/NAC — generally premature for a very small startup unless your environment warrants it.
• Security awareness/phishing platform — beneficial, particularly as headcount grows, but basic training can come first.
• CASB/SASE — generally unnecessary for a tiny organization unless there are specific cloud/remote-work requirements.

If I had a limited budget

I'd prioritize money roughly in this order:

1. MFA + identity security
2. Endpoint protection/EDR
3. Secure email configuration
4. Backups
5. Patching/device management
6. Firewall/network security
7. Password manager + encryption
8. Employee security training
9. Advanced security products

That's because an attacker doesn't care how impressive your firewall is if they can simply steal an employee's Microsoft 365 credentials.

CISA recommends MFA across email, file storage, and remote access, and specifically recommends moving toward phishing-resistant MFA where possible.

A good 10-person startup can therefore have a quite respectable security baseline without buying ten different security products: secure cloud identity/email, MFA, managed endpoints, a decent firewall, backups, patch management, password management, and sensible policies.

If you tell me whether the company is Microsoft 365 or Google Workspace, Windows/Mac, number of employees, and whether there's a physical office, I can give you a concrete "buy these 5–7 things / don't buy these yet" architecture and budget.

For a small company just starting out, building a lean and effective security stack is all about maximizing protection without drowning in software or bloated subscription costs. Because modern threats target identity and endpoints immediately, prioritizing the right baseline is critical.

Must-Have Baseline Security Products

• Endpoint Protection / Next-Gen Antivirus (EDR/NGAV) : This is non-negotiable. Traditional signature-based antivirus is no longer enough. You need an Endpoint Detection and Response (EDR) solution (such as Microsoft Defender for Business, CrowdStrike Falcon, or SentinelOne) running on every company laptop and desktop. It actively blocks malware, ransomware, and suspicious behavioral anomalies.
• Email Security & Phishing Protection : Over 90% of cyberattacks start with a phishing email. While basic mail providers (like Google Workspace or Microsoft 365) offer native filtering, a dedicated secondary layer or advanced configuration (such as Abnormal Security, Avanan, or enhanced Microsoft/Google security tiers) is a must-have to catch credential harvesting and malicious attachments before they hit an employee's inbox.
• Identity and Access Management (IAM) / Multi-Factor Authentication (MFA) : Though not strictly a traditional "product" category listed in your prompt, MFA is an absolute must-have tied directly to your perimeter and email security. Enforcing phishing-resistant MFA (via tools like Duo, Okta, or native Azure AD/Entra ID) protects against stolen passwords, which is the #1 vector for small business breaches.

Optional or Deferred Security Products

• Hardware Firewall (for physical offices) : If your team is fully remote or hybrid working out of home offices and coffee shops, a traditional enterprise hardware office firewall is largely optional. Your immediate focus should be securing the endpoint device rather than a physical office perimeter. However, if you have a physical brick-and-mortar office with local servers or wired networks, a basic business-grade firewall (like Fortinet Go to product viewer dialog for this item. or Ubiquiti UniFi Go to product viewer dialog for this item.) becomes necessary.
• Security Information and Event Management (SIEM) : For a newly launched small business, a full-scale SIEM tool is massive overkill and too expensive/complex to manage. Rely instead on the built-in alerting and logging dashboards provided by your EDR and email security platforms.
• Data Loss Prevention (DLP) Suites : Advanced enterprise DLP tools are optional early on. You can achieve 80% of the benefit by enforcing basic cloud storage sharing rules (e.g., restricting public link generation in Google Drive or SharePoint) rather than buying specialized monitoring software.

If you'd like, tell me:

• How many employees you have
• Whether your team is remote, hybrid, or in an office
• What cloud ecosystem you are using (Google Workspace vs. Microsoft 365)

I can give you a tailored product roadmap and specific software recommendations.

For a startup, choosing the right security stack is a balancing act between protecting your assets and keeping overhead manageable. Here is a breakdown of what is an absolute must-have versus what can be treated as optional for day one.

Must-Have Security Products (Day One Priorities)

• Endpoint Detection and Response (EDR) / Next-Gen Antivirus (NGAV) : Legacy signature-based antivirus is no longer enough. Modern EDR/NGAV solutions (like Microsoft Defender for Endpoint, CrowdStrike, or SentinelOne) actively monitor behavioral anomalies, isolate infected machines automatically, and protect laptops whether they are in the office or at a remote employee's kitchen table.
• Email Security & Phishing Protection : Over 90% of cyberattacks start with an email. While platforms like Google Workspace or Microsoft 365 come with basic built-in filtering, a robust secondary layer (such as Avanan, Abnormal Security, or Ironscales) is critical to catch sophisticated credential harvesting, business email compromise (BEC), and zero-day phishing links before they hit an employee's inbox.
• Cloud Identity and Access Management (IAM) & Multi-Factor Authentication (MFA) : This functions as your modern software perimeter. Enforcing phish-resistant MFA (like hardware keys or app-based push notifications via Okta, Duo, or Microsoft Entra ID) across every corporate tool—especially email, cloud storage, and payroll—is the single highest-return security control you can implement.

Optional Security Products (Can Wait Until Growth/Scale)

• Next-Generation Firewall (NGFW) / Hardware Appliance : If your startup is entirely cloud-native with remote or hybrid employees, a physical hardware firewall for an office is largely optional. Standard stateful firewalls built into your commercial Wi-Fi routers (or cloud-managed edge security like Cloudflare One / Prisma Access if you need zero-trust network access) are plenty for early stages.
• Security Information and Event Management (SIEM) : Full-scale SIEM platforms aggregate logs across your entire enterprise and require dedicated personnel (or an expensive Managed Detection and Response partner) to monitor alerts. Early-stage startups should rely on the native logging and alert mechanisms built into their cloud infrastructure (AWS CloudTrail, Google Cloud Logging, M365 Defender portal) rather than buying a standalone SIEM.
• Data Loss Prevention (DLP) Suites : Advanced enterprise DLP tools that prevent specific intellectual property from leaving the network are complex and expensive to tune. For a small team, standard cloud storage sharing permissions (restricting public link generation in Google Drive or SharePoint) handle 80% of the risk with zero extra software cost.
• Dedicated Vulnerability Scanners : While scanning for network or software vulnerabilities is important, running enterprise-grade external scanners is optional initially if you use managed SaaS platforms. Most cloud infrastructure providers and code repositories (like GitHub's built-in Dependabot) handle basic vulnerability tracking for free.

If you'd like, let me know:

• Your tech stack (e.g., Google Workspace vs. Microsoft 365, AWS vs. Azure)
• Whether your team is fully remote or in an office
• Your industry/regulatory environment (e.g., handling healthcare data, fintech, or general B2B SaaS)

I can tailor a specific product recommendation and budget estimate for your startup.

For a small company just starting, the goal is not to buy every security product. The goal is to cover the most likely attack paths: email compromise, stolen credentials, malware/ransomware, and lost devices. NIST and the FTC both emphasize foundational controls like MFA, updates, antivirus, backups, secure networks, and email protections before moving into advanced tooling.

A practical baseline:

Reasonable starter stack (small office, ~1–25 employees)

Must-have budget tier

• Microsoft 365 Business Premium or Google Workspace with security features enabled
• MFA everywhere
• Managed endpoint protection (business AV/EDR)
• Business firewall/router
• Cloud backup
• Password manager
• Basic security awareness training

Optional early upgrades

Usually not needed on day one

• ❌ Standalone SIEM
• ❌ 24/7 security operations center
• ❌ Penetration testing every quarter
• ❌ Expensive network appliances for a tiny office
• ❌ Multiple overlapping antivirus products

A simple priority order if money is tight

1. MFA everywhere
2. Secure email + domain protections
3. Managed endpoint protection
4. Reliable backups
5. Firewall/router security
6. Password manager
7. Employee training
8. Advanced monitoring/security tools

One common mistake is buying a premium firewall while leaving email accounts protected only by passwords. For a small company, identity + email + endpoints usually matter more than a complex network stack.

If you share the company size, whether everyone is remote or office-based, and whether you use Microsoft 365 or Google Workspace, I can suggest a more specific starter stack.
