Most security conversations start with a question nobody can answer on the spot: what does our company actually look like from the outside?
Not what the architecture diagram says. Not what was true when the last penetration test was signed off. What an outsider — with no access, no credentials, and no relationship with you — can see about your domain right now, using nothing but public information.
There’s a free way to check: Exposure Snapshot.
What it is
Exposure Snapshot is a passive security check for any domain. You type in a domain, it runs a handful of checks from the outside, and it gives you back a graded report of what it found.
Three things about it are worth stating plainly, because they’re the questions everyone asks first:
- It’s free. No credit card, no trial clock, no sales call attached.
- There’s no login. You don’t create an account, and you don’t have to give an email address. There’s an optional email field if you want the full report delivered, and it stays optional.
- It’s passive. Nothing intrusive is sent to the domain you enter. The checks read what’s already public — the same information any visitor, customer, or attacker could look up without asking anyone’s permission.
That last point matters more than it might sound. “Passive” is the difference between observing and poking. A traditional vulnerability scanner sends traffic designed to provoke a reaction, which is why you need written authorization before pointing one at anything. A passive check doesn’t do that. It reads what’s already been published to the world.
In plain English: this is the security equivalent of walking past a building and noting which windows are lit and which doors are propped open. You haven’t touched anything or gone inside — you’ve just looked at what was already on display.
What you get back
The report comes back as a letter grade and a score out of 100, then breaks down into individual checks. Each one is a card: what was checked, whether it passed, and — where something’s wrong — the specific finding with a severity attached to it.
The grade is deliberately blunt. An A doesn’t mean you’re safe, and an F doesn’t mean you’re about to be breached. It means: here is how much this domain is currently telling strangers, ranked by how much it matters. Some checks come back with lists rather than a pass or fail, and if the list is long, the full version goes out by email so the page stays readable.
It takes a few seconds. There is nothing to install.
What it is not
Being honest about the boundary is the whole point, so: this is a preview, not an assessment.
Exposure Snapshot looks at one domain, at one moment, through a handful of checks. It doesn’t know what else you own. It can’t see anything behind your firewall. It doesn’t know whether a credential belonging to one of your staff turned up on a criminal forum last week, and it has no visibility into your cloud accounts.
Those are exactly the gaps that a one-time external check always leaves — and they’re the reason Helios by Isaphia is built as four modules rather than one scanner:
- External ASM — continuously discovers and monitors every internet-facing asset you own, not just the domain you happened to type in.
- Internal ASM — maps what’s reachable behind the firewall, where attackers go once they’re in.
- CTI — threat intelligence matched against your real inventory, so a leaked credential is tied to the portal it actually opens.
- CSPM — continuous configuration auditing across AWS, Azure, and GCP.
The snapshot shows you one frame. The platform shows you the film — and, more importantly, how the frames connect, because real attacks are chains that run across all four views at once.
Who this is useful for
If you’re evaluating your own security posture, it’s the cheapest possible first data point. You’ll know in a minute whether your externally visible configuration is in reasonable shape or quietly leaking.
If you’re a consultant or MSP, it’s a fast way to open a conversation with a prospect using their own domain instead of a slide about industry averages.
If you’re not technical and you’ve been told “we’re fine,” it’s a way to see for yourself, in language that grades rather than lectures. You don’t need to interpret raw output — you get a grade and a list of what’s wrong.
If you’re checking a domain you don’t own — a supplier, an acquisition target, a partner you’re about to integrate with — the passive design is exactly why that’s reasonable. You’re reading public information, not testing their systems.

If what comes back makes you want the continuous version rather than the single frame, self-registration is open: create a free Helios account, point it at your domain, and see the whole surface instead of one slice of it.
Helios by Isaphia is a unified exposure-management platform — External ASM, Internal ASM, CTI, and CSPM in one dashboard — that helps organizations discover, monitor, and protect everything an attacker could reach, before attackers exploit it.
