Keepnet Incident Responder vs KnowBe4 PhishER Plus: Side-by-Side Comparison (2026)

Keepnet Incident Responder

Security teams under siege from phishing will find Keepnet Incident Responder's automation genuinely useful; the platform removes detected threats across inboxes and archives in minutes rather than hours, which matters when your inbox is the attack surface. The 20+ integrated analysis engines and direct Office 365/Google Workspace connectors mean you're not manually exfiltrating emails to third-party sandboxes. Skip this if you need post-incident forensics and recovery workflows; Keepnet prioritizes detection and containment over the investigation depth that larger breaches demand.

KnowBe4 PhishER Plus

Security teams at SMBs and mid-market companies drowning in phishing reports will see immediate ROI from PhishER Plus because one-click removal actually stops attacks instead of just flagging them. The platform handles 13 million global users' threat data and pulls incident response into the hands of non-experts through automated categorization and PhishRIP, which removes malicious emails across all mailboxes simultaneously. Skip this if your organization has a mature SOC already running advanced email security with custom incident playbooks; PhishER Plus shines when you lack dedicated response capacity, not when you need to replace it.
