What Sucuri SiteCheck actually does
Sucuri SiteCheck is a free remote scanner focused on malware detection. It was built as a lead generator for Sucuri's paid website firewall and malware removal services. The scanner checks for:
- Known malware signatures (iframes, obfuscated JavaScript, injected code)
- Blacklist status on Sucuri's and third-party lists
- Spam injection indicators
- Defaced pages
- Basic software version detection (WordPress, Joomla, Drupal)
- A few HTTP security headers
It's fast and does one thing well: tells you if your site is currently infected.
What ismycodesafe.com does differently
We built ismycodesafe.com as a comprehensive vulnerability scanner, not just a malware detector. The goal is to answer "is my code safe to ship?" — which requires checking dozens of attack vectors, not just known infections.
Our 160+ checks include everything Sucuri does (malware via VirusTotal, blacklist checks via Spamhaus) plus:
- OWASP Top 10 mapping: Every finding mapped to OWASP 2021 categories with A-F grading
- CVE detection: Tech stack fingerprinting with NVD and OSV API lookups
- Deep SSL/TLS: SSLyze-powered analysis for Heartbleed, CRIME, weak ciphers, protocol downgrades
- 53 sensitive file paths: .env, .git, backups, CI configs, cloud credentials
- Shodan InternetDB: Exposed ports and known CVEs for your server IP
- Certificate Transparency: Subdomain discovery via crt.sh logs
- JS library vulnerabilities: retire.js-based CVE detection for detected JavaScript libraries
When malware scanning matters more
If you're running a WordPress site and Google just flagged you as "This site may harm your computer," Sucuri SiteCheck will tell you exactly which files are infected. That's their core competency. They also offer paid cleanup services that fix the infection.
ismycodesafe.com won't give you file-level malware forensics. We use VirusTotal (which aggregates 70+ antivirus engines) to check if your URL is flagged as malicious, but we don't scan your server files directly.
When comprehensive scanning matters more
If you're a developer shipping new features and want to know "did I introduce any security issues?" — Sucuri won't help. You need a scanner that checks:
- Missing security headers (CSP, HSTS, X-Frame-Options)
- Exposed .env files or .git directories
- CORS misconfigurations
- Outdated JavaScript libraries with CVEs
- Weak SSL/TLS cipher suites
- Information disclosure in error pages
That's where ismycodesafe.com fits. We're built for developers, not for incident response.
Pricing comparison
Sucuri: SiteCheck is free. Their paid plans start at $199.99/year for website firewall + malware monitoring, and $299/year for one-time malware removal.
ismycodesafe.com: Free basic scan covers all 160+ checks. Premium AI-generated report with code fix recommendations is $49 one-time. 30-minute code security consultation is $150.
Using both together
These tools complement each other. If you're serious about website security:
- Run ismycodesafe.com weekly to catch new vulnerabilities in your code and infrastructure
- Run Sucuri SiteCheck if you see suspicious behavior on your site (unexpected popups, Google warnings)
- Consider Sucuri's WAF if you're a high-value target for attackers (news site, e-commerce, political)
The honest summary
Sucuri is great at malware detection and cleanup. That's what they built. If you're post-compromise, use them.
ismycodesafe.com is great at vulnerability detection and prevention. If you're pre-compromise (which you should be), use us.
Both are free to try. Sucuri will sell you a firewall. We'll sell you an AI-generated report with code fixes if you want it.
