How to defend against every type of phishing attack. Phishing attacks have gotten more targeted, more varied, and harder to catch with standard defenses alone. Spear phishing, BEC, quishing, smishing, each one requires a different technical and procedural response. In this video, we'll outline a four-step framework that maps specific controls to each threat type.

Map each phishing type to specific controls. Different attacks require different responses. Here's the breakdown. Spear phishing and whaling. Enforce DMARC, SPF, and DKIM. Enable external sender tags and require phishing-resistant MFA. Audit mailbox rules weekly and add callback verification for any sensitive requests. Clone phishing and credential harvesting. Use time-of-click URL scanning and attachment sandboxing. Block macro-enabled Office files where business requirements allow and high-risk extensions like .js or .exe. BEC and vendor fraud. Require dual approval for payment changes, maintain trusted vendor allow lists, and quarantine display name spoofing attempts. Build a voice verify checklist for finance teams. Smishing and vishing. Roll out number-matching MFA to reduce MFA fatigue attacks. Run voice and SMS simulations quarterly so users recognize what a real social engineering attempt sounds like. Quishing. Treat every QR code like an unknown URL. Require MFA re-authentication for high-risk actions initiated from QR scans. Angler and social phishing. Use brand monitoring services to catch lookalike social profiles and limit corporate credentials for social SSO logins. The implementation sequence matters. Start with foundational email authentication and phishing protections, then layer on impersonation detection, mailbox monitoring, and advanced user protections. Standardize your baseline first, then layer in impersonation detection and mailbox rule monitoring once that foundation is consistent. Train behaviors. Technical controls fail when users comply with fraudulent requests. Reinforce these four behaviors. Verify out-of-band. Confirm anything involving money or credentials through a separate channel before acting. Inspect before clicking. Hover over links, check for misspelled or lookalike domains, and treat QR codes like unknown URLs. Report, don't engage. Add a Report Phish button in mail clients and recognize employees who catch real threats. Protect MFA prompts. Any MFA prompt a user did not initiate should be denied immediately. Run a repeatable response runbook. When something gets through, structure matters. First, triage by capturing evidence before deleting anything. Contain by revoking active user sessions, quarantining related emails, and resetting compromised credentials if necessary. Make sure to notify users and leadership clearly and escalate fast if finance or data is involved. Then improve by feeding the incident back into your simulations and blocklists. Track metrics. Watch phishing simulation failure rate and user reporting rate on the user side. On the technical side, track DMARC pass rate, blocked lookalike or typosquatted domains, and risky OAuth grants. Review these metrics monthly. A falling failure rate paired with a rising report rate confirms that training and controls are working together. Phishing isn't a single threat. It's a constantly evolving set of tactics, each designed to exploit a different weakness in your environment or your users. For MSPs and IT teams managing multiple clients, a proactive, layered approach to phishing defense is the most effective way to reduce risk.
