A software security audit isn't about finding every vulnerability — it's about closing the most common entry points that attackers exploit.

43%

of cyberattacks target small businesses

Security audits are not optional for enterprises, they are essential for every business.

Most small businesses believe they are too small to be targeted. Attackers know small businesses have weaker defenses.

Software security audit checklist

Verify MFA is enabled on all critical accounts
Review user permissions and remove outdated access
Confirm data encryption at rest and in transit
Check software is up to date with security patches

Only 14% of small businesses have the security tools in place to defend against common cyber threats.

The average small business has 10-20 SaaS tools, each with its own security configuration. A security audit systematically checks each one for the most common vulnerabilities.

The security audit checklist

Essential security checks

Multi-factor authentication enabled on every tool that supports it
Single sign-on (SSO) configured for centralized access control
Orphaned accounts from former employees deactivated
Shared logins eliminated — every user has individual credentials
Access review: no user has more permissions than their role requires

80%

of breaches involve compromised credentials

Weak or compromised passwords are the entry point for 80% of data breaches. MFA alone prevents 99.9% of password-based attacks.

The most impactful security improvement is also the simplest: enable multi-factor authentication on every tool. It prevents 99.9% of automated attacks and requires no user training beyond the initial setup.

The security gap that most SMBs miss is third-party integrations. A tool connected to your CRM via API can access your data even if the tool itself has strong security. Audit integrations quarterly.

Security isn't just about each tool individually — it's about how they connect. An integration with an insecure partner tool can expose your data even if your primary tools are locked down.

70%

risk reduction from quarterly security audits

Businesses that perform quarterly security audits reduce their breach risk by 70% compared to those that never audit.

A software security audit isn't about finding every vulnerability — it's about closing the most common entry points that attackers exploit.

How to audit without expertise

Use a security questionnaire: a standard set of questions that every vendor must answer before contract signing. Tools like Vanta, Drata, and Secureframe provide templates, or you can build your own. The questionnaire should cover the four buckets above and require specific evidence, not marketing language. Then verify: request SOC 2 reports, penetration test results, and certificates. If a vendor refuses to share security documentation, that's a signal.
