Security Audit in 10 Minutes — Your Agent Found 23 Vulnerabilities
Key Takeaway
The Security Audit skill performs comprehensive vulnerability scanning across your infrastructure — open ports, SSL configuration, dependency vulnerabilities, misconfigured permissions, exposed secrets, and outdated packages. Get a prioritized remediation plan instead of a 200-page report nobody reads.
The Problem
Security audits typically happen:
- Never (most startups)
- Once a year (compliance-driven companies)
- After a breach (too late)
The cost of a proper security audit: $10,000-$50,000 from a consulting firm. The deliverable: a 200-page PDF that gets filed and forgotten. The follow-up: maybe 30% of findings get remediated.
Meanwhile, your servers have:
- Open ports you forgot about
- SSL certificates with weak cipher suites
- npm packages with known CVEs
- .env files committed to Git (three repos ago, still in history)
- SSH with password auth enabled
- Default credentials on admin panels
- Docker containers running as root
The Solution
The Security Audit skill runs structured vulnerability assessments and produces actionable, prioritized remediation plans — not 200-page reports.
The Process
View details
You: Run a security audit on our production setup:
- 3 Ubuntu 22.04 servers (web, api, db)
- Node.js API + Next.js frontend
- PostgreSQL 16
- Redis
- All behind Cloudflare
- Git repos on GitLab
The agent produces a structured security assessment:

## Security Audit Report — Production Environment
### CRITICAL (fix immediately) 🔴
1. SSH Password Authentication ENABLED (all 3 servers)
Risk: Brute force attacks
Fix: /etc/ssh/sshd_config → PasswordAuthentication no
Command: sed -i 's/PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config && systemctl restart sshd
2. PostgreSQL listening on 0.0.0.0:5432
Risk: Database accessible from internet
Fix: postgresql.conf → listen_addresses = 'localhost,10.0.0.0/24'
URGENT: This is actively exploitable
3. 7 npm packages with HIGH/CRITICAL CVEs
Packages: lodash (prototype pollution), jsonwebtoken
(signature bypass), express (ReDoS)
Fix: npm audit fix --force (test in staging first)
### HIGH (fix this week) 🟠
4-8. [SSL cipher suite issues, missing security headers,
Redis no auth, Docker root containers]
### MEDIUM (fix this sprint) 🟡
9-16. [Log rotation, backup encryption, rate limiting,
CORS configuration, CSP headers]
### LOW (track and schedule) 🔵
17-23. [Minor version updates, informational findings]
### REMEDIATION PRIORITY
| # | Finding | Effort | Impact | Priority Score |
|---|---------|--------|--------|---------------|
| 2 | Postgres exposed | 5 min | Critical | 🔴 10/10 |
| 1 | SSH password auth | 5 min | Critical | 🔴 10/10 |
| 3 | npm CVEs | 30 min | High | 🟠 8/10 |
| 5 | Redis no auth | 10 min | High | 🟠 8/10 |
...
Total remediation time estimate: 4-6 hours
The Results
| Metric | Annual Audit Firm | AI Security Audit |
|---|---|---|
| Frequency | Once/year | On-demand (anytime) |
| Cost | $10,000-50,000 | ~$0.20 per run |
| Deliverable | 200-page PDF | Prioritized action list |
| Time to results | 2-4 weeks | 10 minutes |
| Remediation rate | ~30% | Higher (actionable format) |
| Follow-up scans | Next year | Run again after fixes |
