CyCognito Active Security Testing
Security teams responsible for external attack surface management should pick CyCognito Active Security Testing because its multi-pass testing architecture actually finds vulnerabilities that single-pass scanners skip, then surfaces them with discoverability and attractiveness scoring so you stop triaging noise. The platform covers ID.AM and ID.RA functions across cloud and on-premises infrastructure simultaneously, which matters when your external footprint spans multiple hosting providers. Skip this if you need integrated remediation workflows or threat intel feeds; CyCognito is strictly the testing layer, not the ticketing system.
Application security teams with limited budgets who need both automated scanning and manual testing capability will get the most from Grendel-Scan, since it covers both attack vectors in a single free tool without forcing you to patch together open-source utilities. The dual approach means you're not choosing between speed and depth; you run automated scans for baseline coverage, then layer manual penetration testing for logic flaws and business logic bypasses that scanners miss. Skip this if your org requires vendor support contracts, formal SLAs, or integration with a ticketing system; Grendel-Scan is built for teams comfortable operating independently.
