Six layers of intelligent analysis working simultaneously on every message in your inbox — without reading a single word.

Phishing Detection
Identifies credential-harvest campaigns, fake login pages, and lookalike domains. Catches attacks that pass standard spam filters.
Malware Signatures
Scans attachment metadata against known malware patterns. Detects Office macro exploits, PDF threats, and compressed archive payloads.
Suspicious Link Analysis
Resolves redirect chains and detects URL shorteners masking malicious destinations. Flags anchor text mismatches and typosquatted domains.
SPF / DKIM / DMARC
Full authentication header analysis on every message. Detects spoofed senders and domain impersonation even when certificates appear valid.
Attachment Intelligence
Analyses file types, double extensions, password-protected archives, and embedded scripts — before any file is opened or downloaded.
Threat Report
Delivers a structured security report with risk scores, finding summaries, and actionable recommendations — not just a list of flags.

Customer stories
Trusted by security-conscious professionals
Sentinel flagged a sophisticated spear-phishing campaign targeting our finance team that had been running for three weeks. The DMARC analysis alone was worth it.

IT Security Lead, Nairobi
I was sceptical about connecting my inbox, but the read-only OAuth is genuinely reassuring. The report found a credential-phishing thread I had missed for months.

Anika L.
Freelance Consultant, Barcelona
The attachment intelligence caught a macro-laden Excel file that our AV missed entirely. The report was clear, actionable and explained the exact risk level in plain language.
