Phishing is the most common initial attack vector for data breaches, according to the IBM 2024 Cost of a Data Breach Report. The average breach costs $4.88 million. And 90% of ransomware attacks start with a single phishing email.
The right anti-phishing solution stops these attacks before they reach your users. But “the right solution” means different things for a 25-person company versus a 5,000-person enterprise. This checklist helps you evaluate what you actually need - based on 2026 threat landscape expectations, not marketing claims.
Use this as a scoring guide. Check off what your current solution covers. Any gaps are risk.
The 11-Point Anti-Phishing Protection Checklist
1. Multi-Engine Threat Detection
Why it matters: No single threat intelligence database catches everything. Attackers routinely evade one vendor’s signatures while being caught by another.
What to look for:
- Multiple detection engines running simultaneously (not sequentially)
- Cross-references URLs and attachments against different threat intelligence feeds
- Combines signature-based detection with behavioral/AI analysis
- Catches zero-day threats that no single database has seen yet
“No single threat intelligence database catches everything. That’s why Phish Protection cross-references every email against Vade Secure, Sophos, Halon Classify, Webroot BCTI, and proprietary weighting algorithms simultaneously.” - Adam Lundrigan, CTO, DuoCircle
Phish Protection: ✅ 5 engines + proprietary weighting algorithms
2. Real-Time Scanning (Pre-Delivery)
Why it matters: Scanning emails after they’ve been delivered means users see threats before they’re blocked. Pre-delivery scanning stops threats at the gateway.
What to look for:
- Inline scanning before the email reaches the inbox
- Millisecond-level processing (no noticeable delivery delay)
- Scans headers, body content, URLs, and attachments in a single pass
Phish Protection: ✅ Pre-delivery gateway scanning with sub-second latency
3. Time-of-Click URL Protection
Why it matters: Attackers now send emails with clean URLs that are weaponized hours later - after traditional filters have already cleared the message. This is called delayed weaponization, and it bypasses every solution that only checks links at delivery time.
What to look for:
- URL rewriting so every link routes through a scanning proxy
- Re-analysis at the moment a user clicks, not just at delivery
- Handles redirect chains and URL shorteners
- Blocks links that became malicious after the email was delivered
“Time-of-click protection is the single most important advancement in email security in the last five years.” - Brad Slavin, General Manager, DuoCircle
Phish Protection: ✅ Every URL rewritten and re-scanned at click time
4. Business Email Compromise (BEC) Detection
Why it matters: BEC attacks cost organizations $125,000 per incident on average (FBI IC3 2024). These attacks don’t use malware or malicious links - they impersonate executives and request wire transfers or credential changes.
What to look for:
- Display name spoofing detection
- Domain impersonation detection (lookalike domains)
- Behavioral analysis of sender patterns
- First-contact safety warnings for new or unusual senders
- Executive impersonation protection
Phish Protection: ✅ BEC detection including display name and domain impersonation
5. Email Authentication Enforcement (SPF, DKIM, DMARC)
Why it matters: Since February 2024, Google and Yahoo require SPF + DKIM + DMARC for bulk senders. Starting May 2025, Microsoft rejects email failing DMARC from high-volume senders. If your domain isn’t authenticated, your own emails get rejected - and attackers can spoof your domain freely.
What to look for:
- SPF, DKIM, and DMARC validation on all inbound email
- Alignment checking (From header matches authentication domain)
- Reporting on authentication failures
Phish Protection: ✅ Full SPF/DKIM/DMARC validation. For dedicated DMARC monitoring, see DMARC Report. For SPF flattening, see AutoSPF.
6. Platform Compatibility (Especially Microsoft 365)
Why it matters: Microsoft 365’s built-in phishing protection (Defender for Office 365) consistently underperforms against targeted spear phishing, zero-day URLs, and sophisticated BEC attacks. Google Workspace has significantly stronger native phishing detection - but Microsoft 365, which dominates the enterprise market, leaves dangerous gaps that require a dedicated third-party solution.
What to look for:
- Microsoft 365 support (this is where the biggest protection gap exists)
- On-premise Exchange and SMTP server support
- Google Workspace support (less critical - Google’s native detection is strong)
- No MX record changes required (API-based or mail flow rule deployment)
- Setup in minutes, not days
“Microsoft’s built-in phishing protection in Office 365 catches the obvious attacks, but it consistently misses targeted spear phishing and zero-day threats. We see this every day - customers come to us after an incident that Microsoft Defender didn’t catch.” - Adam Lundrigan, CTO, DuoCircle
Phish Protection: ✅ Purpose-built for Microsoft 365 environments. Also works with Exchange, Google Workspace, and any SMTP-based email. Deploys via mail flow rules in minutes.
7. No Hardware or Software Installation
Why it matters: Solutions that require on-premise hardware or endpoint agents create deployment friction, ongoing maintenance burden, and compatibility issues. Cloud-based solutions deploy instantly.
What to look for:
- Cloud-hosted scanning infrastructure
- No appliances, agents, or desktop software
- No impact on existing email infrastructure
- Works for remote and hybrid workforces automatically
Phish Protection: ✅ Fully cloud-based. No hardware, no agents, no desktop software.
8. Real-Time Dashboard and Reporting
Why it matters: You can’t manage what you can’t see. Security teams need visibility into what threats are being blocked, which users are targeted, and how the overall security posture is trending.
What to look for:
- Real-time threat dashboard
- Historical trend analysis
- Per-user threat exposure reports
- Exportable reports for compliance audits (SOC 2, PCI DSS, HIPAA)
- Customizable alerts (email, SMS, Slack, webhook)
Phish Protection: ✅ Real-time dashboard with historical trends, exportable compliance reports, and multi-channel alerts.
9. Admin Controls (Blocklists, Allowlists, Policies)
Why it matters: Every organization has unique email patterns. A good solution lets you fine-tune protection without creating gaps.
What to look for:
- Custom blocklists and allowlists
- Policy-based filtering rules
- Per-user or per-group policy settings
- Quarantine management with release controls
- Trusted sender/domain configuration
Phish Protection: ✅ Full admin controls including custom blocklists, allowlists, trusted domains, and policy settings.
10. Transparent, Predictable Pricing
Why it matters: Many enterprise security vendors hide pricing behind “contact sales” walls and lock you into multi-year contracts. Small businesses and mid-market companies need predictable costs.
What to look for:
- Published pricing (no “contact us for a quote” as the only option)
- Per-user or per-mailbox pricing
- No long-term contracts required
- Free trial with no credit card
- Ability to scale up or down as your team changes
“When I talk to prospects about phishing protection, I don’t lead with features - I lead with math. A single successful BEC attack costs $125,000 on average. Phish Protection for a 50-person company costs $49 a month. The ROI calculation writes itself.” - Dan Calkin, VP of Sales, DuoCircle
Phish Protection: ✅ Published pricing from $19/month. 60-day free trial, no credit card, no contract. See pricing.
11. 24/7 Support from Real Humans
Why it matters: When a phishing incident happens, you need help immediately - not a chatbot, not a 48-hour SLA, not a knowledge base article.
What to look for:
- 24/7 availability
- Phone, email, and live chat
- US-based or in-region support team
- Dedicated account manager for larger deployments
- Fast response times (under 1 hour for critical issues)
Phish Protection: ✅ 24/7 US-based support via phone, email, and chat. Contact support.
