The question every alert leaves unanswered
Your security tools are good at telling you that something is wrong. A GuardDuty alert fires. A misconfiguration surfaces. A vulnerable Lambda gets flagged. But every one of those findings leaves the same question hanging in the air:
So what? What can an attacker actually reach from here?
Until now, answering that meant hours of manual detective work. An analyst would start at the flagged EC2 instance, check which roles it could assume, then which storage buckets those roles could open, then whether any of those buckets were reachable from a connected network, and on, and on. Every step meant a different console, a different tool, and a different piece of tribal knowledge about how your cloud is wired together. It was slow, and it was almost never complete.
Blast radius answers that question in seconds: from this resource, what can be reached, and how bad would it be?
What it catches that point tools miss
A single finding rarely lives in isolation. The risk is in the chain of access that finding sits on top of, and that chain usually spans multiple cloud concepts that no single dashboard shows together. Blast radius is built to follow those chains:
Hidden lateral movement. An instance with overly broad permissions can quietly assume a role that reads your production secrets. That path was invisible unless you already knew to go looking for it.
Cross-network exposure. A resource in a dev environment, connected to production through network peering with the right routing and firewall rules, can reach your production databases. That path crosses three separate networking concepts at once, exactly the kind of thing that slips through manual review.
Wide-open access. A policy that grants access to everyone is one of the most dangerous configurations in the cloud, and one of the easiest to miss. Blast radius flags these resources explicitly, even when there's no obvious connection on the map.
Context that changes the call. When an alert fires, what matters isn't just the affected resource. It's whether that resource can reach your payment database. That single fact can change a low-priority ticket into an all-hands incident.
How it works, without the plumbing
The idea is simple, even though the engineering behind it isn't.
First, we continuously build a live map of your cloud, capturing every resource and every connection between them: who can assume which roles, which networks can talk to which, and what's exposed to the internet. Think of it as a wiring diagram that stays current as your environment changes.
Then we do the hard math ahead of time. Tracing every possible path through a real cloud account is expensive, so instead of making you wait while we calculate it on the spot, we compute the paths in the background and keep the results ready. When you open a finding, the answer is already there.
Finally, we layer live risk information on top, things like current severity, confidence, and risk scores, so the map you see reflects what's actually dangerous right now, not a snapshot from last week. The result is an interactive graph you can explore: color it by risk level or resource type, hide the noise, and zoom in on the paths that matter. Even sprawling environments with hundreds of connected resources stay readable.
A few of the hard problems we solved
Two things turned out to be trickier than they look and getting them right is a big part of what makes blast radius trustworthy.
The first is wide-open access policies. A resource that's open to "everyone" doesn't show up as a normal connection on the map. There's no single line pointing from it to "everything." We detect these cases specifically and surface them anyway, so a dangerously permissive policy never hides just because it doesn't fit the usual pattern.
The second is identity matching across tools. Different security sources describe the same resource in different ways. Your runtime monitoring, your threat detection, and your container scanning each have their own naming conventions. We reconcile all of them back to a single source of truth. Without that, a real attack path can quietly show up as "nothing to see here," which is the worst possible failure mode in security. We built blast radius to fail loudly, not silently.
And because it works the same way across AWS and Azure, even though the two clouds model identity and networking very differently under the hood, you get one consistent view no matter where your workloads run.
Where teams actually use it
Triage an incident in under five minutes. When an alert fires on an instance, the analyst opens the blast radius view and immediately sees whether that instance can reach buckets holding sensitive data, whether it can assume roles with cross-account access, and how many hops away the crown jewels are. That changes the priority and the response plan before any manual investigation begins.
Prioritize vulnerabilities by real exposure, not just CVSS score. A "critical" vulnerability on a function that can only reach an empty database is less urgent than a "medium" on an instance three hops from your payments system. Blast radius puts that context right on the vulnerability record, so your team fixes what's genuinely dangerous first.
Connect incidents that look unrelated. A finding on a dev function and a misconfiguration on a staging database can seem like two separate events, until you realize the function has access to a role that can reach that database. Blast radius automatically spots when two incidents share an attack path, surfacing the connection no analyst was looking for.
Audit your network proactively. Teams don't just use blast radius after something breaks. They pick a resource and ask, "Who can reach this?" to audit whether network connections set up for convenience have quietly opened a door to sensitive systems. It shows the routing rules, the firewall rules, and the peering relationship in one view, which no native cloud console does.
The bottom line
Findings tell you where to look. Blast radius tells you why it matters. Instead of an analyst spending hours stitching together consoles to figure out what an attacker could reach, the answer is on the screen the moment the alert lands, turning a pile of disconnected findings into a clear, prioritized picture of real risk.
