Compare/Check Point Harmony / Avanan

Cambrient vs.
Check Point Harmony, evolved.

Harmony and Avanan are API-based like Cambrient, a genuine step forward from SEG architecture. But there is a critical architectural flaw that creates a protection blind spot, and the detection is still signature-based, not agentic.

Emails between Harmony customers bypass both Harmony and Microsoft Defender
The architectural flaw

The safelisting problem that creates a blind spot.

To prevent mail loops, Harmony must safelist its own server IP addresses in Microsoft's mail flow. This means emails sent from one Harmony customer to another bypass both Microsoft's Exchange Online Protection and Harmony's own filtering. An attacker who also subscribes to Harmony can send phishing emails to any other Harmony customer completely unfiltered.

Victim INBOX
1
Email sent from Check Point customer A to Check Point customer B
2
Microsoft receives email. Tries to route to Harmony for filtering.
3
Harmony recognizes its own server as sender. To avoid a mail loop, it safelists it.
4
Email bypasses Harmony filtering entirely.
5
Email bypasses Microsoft Defender filtering entirely (safelisted).
6
Malicious email delivered directly to inbox, zero filtering.
Why Cambrient doesn't have this problem

Cambrient connects via read and analyze API permissions, not as a mail transport. We never insert ourselves into the mail flow, never require safelisting of any IP addresses, and never create conditions for a mail loop. Every email is analyzed regardless of sender, including emails from other Cambrient customers. There is no blind spot.

Beyond the flaw

Even without the blind spot, Harmony falls short.

Still signature-based detection
Harmony connects via API but its classification engine is still signature and reputation-based. It doesn't crawl link destinations in real time, doesn't render pages, and doesn't reason about behavioral intent.
No plain-English user explanation
Like most enterprise security tools, Harmony quarantines silently. End users don't understand what was blocked or why, leading to IT tickets and the dangerous habit of marking quarantine emails as safe.
Not built for MSPs at scale
Harmony is an enterprise product with enterprise pricing and complexity. Its multi-tenant capabilities are limited compared to Cambrient's purpose-built MSP dashboard with global rules, cross-tenant remediation, and per-seat pricing.
No self-service false positive release
False positives in Harmony require analyst or IT admin action to release. Cambrient lets end users release false positives themselves from the banner in their inbox. No ticket, no wait.
