About SurfaceDiff
SurfaceDiff is an external attack surface change monitoring service. It scans public domains, subdomains, DNS records, open ports, TLS certificates and web services on a schedule. It then compares each scan with the previous one to show what has changed. The company sells to hosting providers, managed service providers, managed security service providers, managed cloud teams and data centre operators. It also serves teams that manage many domains on shared infrastructure. The service works by taking recurring snapshots and normalising them into a single structured record. New hosts, ports, certificates or services are detected and reported as incidents with timestamps and supporting evidence. Users can mark known exposures as reviewed so future scans stay quiet about them. Shared servers are treated as one entity, so a single change on a shared host produces one incident rather than many. Pricing is token-based, counting each domain and each distinct server once. SurfaceDiff is built and operated by ITC - IT Consulting in Pyskowice, Poland.
