A security audit is a structured review of your website and infrastructure’s security posture — useful both as a one-time health check and periodically as the business and its risk profile grow.
What a thorough audit covers
- SSL/TLS configuration (certificate validity, supported protocol versions)
- DNS configuration and email authentication (SPF/DKIM/DMARC)
- Software and dependency versions checked against known vulnerabilities
- Access control review: who has admin access, and is MFA enforced
- Backup existence and restoration testing, not just backup existence
- Security headers and basic hardening (rate limiting, WAF presence)
- Blacklist/reputation status across major vendors
How often to run one
A full audit annually is a reasonable baseline for most small businesses, with lighter continuous automated monitoring covering the fast-changing items (vulnerabilities, blacklist status, SSL expiry) in between full audits.
FAQ
Can automated tools fully replace a manual security audit?
Automated tools cover a large share of routine checks efficiently, but a periodic manual review still adds value for judgment-based items like access control appropriateness and overall architecture review.
