Acunetix Web Vulnerability Scanner
Development and security teams managing public-facing web applications will get the most from Acunetix Web Vulnerability Scanner because its crawling engine finds logic flaws and chained vulnerabilities that static scanners miss. The tool catches real exploitable paths through your site, not just isolated weaknesses; a single scan typically surfaces 40+ issues on medium-sized applications. Skip this if you need API-first scanning or are hunting for code-level defects in your build pipeline; Acunetix is purpose-built for runtime web application testing, not SAST or microservices architecture assessment.
Startup founders and small business owners running WordPress or similar CMS sites should pick SiteLock Basic for its daily malware scanning and automated backup, which handle the two things that actually tank small sites: compromised code and lost data. The 2GB daily backup paired with continuous monitoring covers both the ID.RA Risk Assessment and PR.DS Data Security functions without requiring your team to manage infrastructure. Skip this if you need vulnerability remediation or incident response; SiteLock Basic finds problems and backs up your site, but the 30-hour support window and lack of automated patching mean you're still fixing things yourself.
