Defense-in-depth isn't just for big companies

Sophisticated security isn't only for enterprises with massive budgets.

The most effective security approach has always been defense-in-depth.

Multiple layers of protection work together. Email filtering catches what endpoint protection misses. Multi-factor authentication prevents credential theft. Vulnerability scanning identifies weaknesses. Air-gapped backups ensure recovery options.

Each layer catches what the others miss.

But here's what's changed:

These enterprise-grade solutions are now accessible to businesses of all sizes.

The tools have become more affordable. Implementation has become more straightforward. Management has become less resource-intensive.

Security is no longer about how much you spend.

It's about how strategically you implement your defenses.

Here’s an example for SMBs.

1. Perimeter Defense – Firewall

Tool: Fortinet FortiGate or Cisco Meraki

Purpose: Blocks unauthorized traffic at the network edge.

2. Network Defense – Intrusion Detection & Segmentation

Tool: Ubiquiti Unifi with VLANs + Snort IDS

Purpose: Monitors and separates internal traffic to limit lateral movement.

3. Endpoint Security – Antivirus & EDR

Tool: CrowdStrike Falcon or SentinelOne

Purpose: Protects individual devices from malware, ransomware, and suspicious behavior.

4. Application Security – Email & Web Filtering

Tool: Proofpoint Essentials or Barracuda Email Security

Purpose: Blocks phishing, malicious links, and attachments.

5. Data Protection – Backup & Recovery

Tool: Datto SIRIS or Veeam Backup for Microsoft 365

Purpose: Ensures quick recovery from data loss or ransomware.

6. Identity & Access Management – MFA & SSO

Tool: Microsoft Entra ID (Azure AD) + Duo MFA

Purpose: Protects user accounts and access to cloud apps.

7. Security Awareness – Human Layer

Tool: KnowBe4

Purpose: Trains employees to recognize and avoid threats.

Is your security approach based on hope or on strategy?
