External exposure research, dark web analysis, and attack surface monitoring methodology from the ThreatPulsar team.
Most companies underestimate the size of their external footprint. Here's a framework for enumerating what's exposed and deciding what actually needs attention.
Not all credential leaks are equal. A fresh dump from a business email domain is a different risk than a three-year-old consumer account breach. Here's how we weight them.
Character substitution, homoglyphs, and brand keyword variations produce domains that evade basic similarity checks. Here's a more complete detection approach.
No single method finds everything. Certificate transparency logs catch what DNS brute force misses. Passive DNS catches what cert logs miss. Here's how to combine them.
S3 buckets, GCS buckets, and Azure Blob storage with public ACLs are still found in the wild regularly. Most were set that way intentionally once and never reviewed again.
Coverage in dark web monitoring is uneven. Some forums index well; others don't. Here's an honest breakdown of where leaked credentials are most likely to surface and where gaps exist.
An exposure score is only useful if you know what it's measuring. We explain the inputs, the weighting logic, and why we treat finding age as a factor.
A phishing domain without an active mail exchanger is still being set up. The window between registration and first send is often measurable. Here's how to use it.
Over-alerting on legitimate CDN subdomains or known-good third-party services erodes trust in the platform. We track false positive rates and here's what's driving them.
CT logs are a free, real-time feed of newly issued certificates. For external monitoring, they're one of the most reliable ways to catch new subdomains. Here's how to work with them.
Multi-tenant external monitoring has different isolation requirements than endpoint or SIEM services. Here's what to think through before deploying it across client environments.
Misconfigured API gateways and forgotten debug endpoints regularly turn up in external scans. Most were exposed during development and never removed. Here's what we find and how.
