Sonar Security Checkup
A managed security assessment of your organization's external posture — delivered by our team. We review email, websites, DNS, brand exposure, open services, reputation, and identity risk, then share clear findings you can act on.
What we assess
Each area is reviewed against public security signals. Findings include scores, grades, and remediation guidance our team can help you implement.
Website security
HTTPS availability, TLS certificates, HSTS, security headers, and mixed content on your public sites.
Trust & compliance
Privacy policy pages, cookie and consent management signals, and trust center or security.txt presence.
DNS posture
DNSSEC, CAA, nameservers, SOA health, and wildcard DNS across your zones.
Brand & phishing exposure
Typosquatting, combosquatting, homograph lookalikes, and certificate transparency signals around your brand.
Exposed services
Remotely reachable admin, database, container, infrastructure, and management ports on public hosts.
Reputation & blocklists
Whether your IPs, domains, and URLs appear on public blocklists and reputation feeds.
Identity & breach exposure
Directory hygiene and breach signals that indicate exposed accounts or weak identity posture.
