Every compliance audit starts the same way: "Show me your security policies." Most SMBs either don't have them, have a Word doc from 2019 that nobody follows, or have policies copied from a Fortune 500 company that make no sense for a 50-person business.
The reality? You don't need a 200-page security manual. You need a handful of clear, practical policies that your employees will actually read and follow.
Here are the six foundational policies every SMB should have — and how to write them without hiring a consultant.
Why Bother With Security Policies?
Before we dive in, let's address the elephant in the room: do security policies actually matter?
Yes, and here's why:
- Compliance requirements. SOC 2, ISO 27001, GDPR, NIS2, and most cyber insurance questionnaires require documented policies.
- Legal protection. If an employee causes a breach, documented policies that they acknowledged protect your organization.
- Clarity for employees. People can't follow rules they don't know. Policies set expectations.
- Enterprise sales. Try selling to a large company without security policies. You'll get stuck in vendor assessment limbo forever.
The key word is documented. Having an unwritten rule that "we don't share passwords" doesn't count. Write it down, get people to sign it, and actually enforce it.
The 6 Essential Policies
📋 1. Information Security Policy
This is the "master policy" — a high-level document that establishes your organization's commitment to security and references all other policies.
What to include:
- Scope (who it applies to)
- Security objectives (confidentiality, integrity, availability)
- Roles and responsibilities (who owns security)
- Reference to supporting policies
- Review schedule
- Executive approval signature
Length: 1-2 pages. Don't pad it.
💻 2. Acceptable Use Policy (AUP)
The policy everyone should sign on day one. Defines what employees can and can't do with company technology.
What to include:
- Personal use guidelines (some is usually OK)
- Prohibited activities (malware, piracy, harassment)
- Email and internet use expectations
- BYOD rules if you allow personal devices
- Monitoring disclosure (yes, you should tell them)
- Consequences for violations
Tone tip: Write like a human. "Don't install random software from the internet" beats "Users shall not execute unauthorized executables from external sources."
🔑 3. Password & Authentication Policy
Stop requiring password changes every 90 days. Seriously. NIST changed their guidance years ago, and you should too.
Modern password policy essentials:
- Minimum 12 characters (longer is better)
- No mandatory expiration (unless compromised)
- MFA required for external access and admin accounts
- Approved authenticator apps (not SMS)
- Password manager recommendations
- What to do if you think you're compromised
🏠 4. Remote Work Security Policy
If you have anyone working from home — even occasionally — you need this. Post-COVID, it's non-negotiable.
Cover these areas:
- Home network security (WPA2/3, router password)
- VPN requirements
- Physical workspace security (screen privacy, lock your laptop)
- Public Wi-Fi rules (hint: always use VPN)
- Video conferencing security
- What to do if a device is lost/stolen
🏷️ 5. Data Classification Policy
Not all data is equal. A marketing brochure doesn't need the same protection as customer PII. Classification helps people make smart decisions about handling data.
Keep it simple — three levels:
- Confidential 🔴 — Sensitive data. Encryption, need-to-know access, no external sharing without approval.
- Internal 🟡 — Business information. Keep it inside the company, but no special handling.
- Public 🟢 — Approved for external release. Marketing materials, published content.
Document what falls into each category and how to handle it. Most importantly: when in doubt, treat it as Confidential.
🚨 6. Incident Reporting Policy
Your best security sensor is your employees — but only if they know what to report and how.
Make it easy:
- Clear definition of what to report (when in doubt, report it)
- Multiple reporting channels (email, phone, Slack channel)
- Expected response times by severity
- What to do immediately (disconnect from network, don't delete anything)
- Non-retaliation clause (critical — people won't report if they fear punishment)
The goal: low friction for reporting, fast response from IT. A phishing email reported in 5 minutes is a lot easier to handle than one reported after someone clicked and provided credentials.
How to Actually Write These
1. Start with structure
Every policy should have:
- Purpose (why it exists)
- Scope (who it applies to)
- Policy statements (the actual rules)
- Responsibilities (who does what)
- Enforcement (what happens if violated)
- Review schedule (when you'll update it)
2. Write for your actual audience
Your employees aren't security professionals. Skip the jargon. If you wouldn't say it out loud in a meeting, don't write it in a policy.
Bad: "Users shall not transmit unencrypted PII across unsecured network segments."
Better: "Don't email sensitive customer data. If you need to share it externally, encrypt the file or use our secure file sharing system."
3. Be specific about exceptions
Every rule will have exceptions. Document how to request them rather than pretending they won't happen.
4. Include real examples
Abstract rules are hard to follow. Give concrete examples of what's OK and what's not.
5. Keep them short
A 30-page acceptable use policy won't be read. Aim for 2-4 pages per policy. If you need more, you're probably trying to cover too much in one document.
Implementation Checklist
Writing policies is only half the battle. Here's how to make them stick:
- Get executive sign-off (policies without leadership buy-in are worthless)
- Train employees (don't just email a PDF)
- Collect acknowledgments (signatures that they've read and understood)
- Make policies accessible (internal wiki, not buried in a SharePoint folder)
- Actually enforce them (inconsistent enforcement undermines everything)
- Review annually (technology changes, so should policies)
Common Mistakes to Avoid
- Copy-paste from enterprise policies. A Fortune 500's security policy doesn't fit a 30-person company.
- Making them too restrictive. If policies prevent people from doing their jobs, they'll find workarounds.
- No enforcement. Policies that aren't enforced teach people that security doesn't matter.
- Set-and-forget. Policies need regular updates as your business and threat landscape change.
- Too much legalese. Readable policies get read.
Compliance Mapping
These six policies cover the core requirements for most SMB compliance needs:
| Policy | SOC 2 | ISO 27001 | GDPR |
|---|---|---|---|
| Information Security Policy | CC1.1, CC1.2 | A.5.1 | Art. 32 |
| Acceptable Use Policy | CC6.1, CC6.7 | A.8.1 | Art. 32 |
| Password Policy | CC6.1, CC6.2 | A.9.2, A.9.4 | Art. 32 |
| Remote Work Policy | CC6.1, CC6.7 | A.6.2, A.11.2 | Art. 32 |
| Data Classification | CC6.1, CC6.5 | A.8.2 | Art. 5, 32 |
| Incident Reporting | CC7.2, CC7.3 | A.16.1 | Art. 33, 34 |
Final Thoughts
Security policies aren't exciting. Nobody's going to put them on LinkedIn. But they're foundational — both for protecting your organization and for meeting the compliance requirements that clients and partners increasingly demand.
The best policy is one that people actually follow. Keep them practical, keep them updated, and keep them enforced.
