SMB and mid-market teams drowning in ransomware and credential theft will find value in Cyber Crucible's sub-200-millisecond autonomous response, which stops attacks before your analysts even see the alert. The patented analytics engine and on-system decision-making handle data theft prevention across desktops, servers, and cloud without requiring a SOC to babysit every incident, addressing the NIST Detect and Respond gap most EDR tools leave open. Skip this if you need mature incident investigation workflows or deep forensic replay; Cyber Crucible prioritizes prevention and root cause storage over post-breach analysis.
Mac-focused security teams with limited budgets should start with Knockknock to audit persistence mechanisms that commodity malware relies on, especially rootkits and launch agents that traditional antivirus misses. It's free and open-source, so deployment friction is near zero and you can inspect the code yourself. Skip this if you need real-time prevention or cross-platform coverage; Knockknock is a forensic scanner for macOS, not an EDR replacement.
