Sentinelle scans your email and web infrastructure every week. If anything changes — degraded DMARC, expiring SSL, orphaned subdomain, blacklist — you're alerted within the hour, before it becomes an incident.
We set up monitoring on your URL. No installation, no access to your server required.
DNS, TLS, IP reputation, abandoned SendGrid/Brevo/AWS subdomains — 6 automated checks.
As soon as a new issue is detected, you get an email with the details and remediation steps.
Permanent access to your portal: score history, trend, list of open issues.
Checks that your DMARC policy is in enforcement mode (p=quarantine or reject) and that SPF and DKIM are correctly configured. A DMARC set to p=none leaves the door open to phishing under your name.
Checks the expiration date, certificate chain and TLS configuration. Alerts 30 days before expiration and detects weak configurations.
Checks whether your sending IP or domain appears on Spamhaus blacklists. A blacklist listing immediately degrades the deliverability of your legitimate emails.
Detects subdomains like em*.domain.com, mail.*, bounce.*, track.* pointing to third-party email services (SendGrid, Brevo, Mailchimp…) that may have been abandoned — a leading vector for authenticated phishing campaigns.
On every cycle, an AI audit analyzes your site against the latest integrated regulations (GDPR, NIS2, Omnibus). New sanctions and case law are automatically included.
A score from 0 to 100 aggregates all checks. The history shows whether your security posture is improving or degrading over time.
Most email security issues are silent — until the day a customer tells you they're receiving phishing emails in your name.
