ASM

Attack Surface Management

Continuous discovery and monitoring of what your organization exposes to the internet. A scanner returns candidates; ASM produces an inventory your team has decided the ownership of, and can defend.

About ASM

Most organizations cannot list what they expose to the internet. A subdomain made for a campaign, a server a contractor set up, a domain inherited in an acquisition: none of them is on any list until someone outside finds it.

ASM finds them in public, passive sources: certificate transparency logs, passive DNS and domain registration data. Each discovery arrives as an ownership proposal with its reasons and a confidence, a person decides, and what is confirmed joins the same asset inventory the assessments use. From then on, monitoring reports change against a baseline.

ASM is part of our security platform; it is built but not yet deployed. Discovery is passive only and sends nothing to your systems; active checks and cloud sources are planned.

From Scan Output to a Defensible Inventory

The work is not finding things. It is deciding who each of them belongs to

1
Discovery Produces Candidates
From the seeds you give it — domains, address ranges, organization names — discovery returns hosts, certificates, services and subdomains. None of them are yet your assets. They are candidates with a confidence level attached.
2
A Person Decides What Is Yours
Confidence is not ownership. Someone accepts, rejects or marks a candidate as third-party, and that decision is recorded with who made it. A marketing agency’s landing page and your payment gateway do not belong in the same bucket.
3
Accepted Assets Join the One Inventory
What you accept becomes an asset in the same inventory your assessments use, with its owner and history — never a second, parallel list that disagrees with the first. And being in the inventory still does not authorize testing it.

Key Features

What keeps the inventory accurate and trustworthy

Discovery From Seeds You Control
Campaigns run from domains, address ranges and organization identifiers you provide, so the scope of discovery is a decision you made rather than whatever a tool guessed.
Ownership Is a Decision, Not a Guess
Every candidate waits for a person to accept, reject or mark it third-party. The decision, the decider and the moment are recorded, which is what makes the inventory defensible later.
Third-Party Assets Stay Visible but Separate
A supplier’s portal that carries your brand is your exposure and someone else’s system. It stays in view, marked for what it is, instead of being deleted or quietly treated as yours.
One Inventory, Not a Parallel One
Accepted discoveries become assets in the same inventory the assessment work uses. There is never a discovery list and an asset list that disagree about what exists.
A Baseline, So Change Means Something
Each discovered subject has an observed baseline: the names an address resolves to, a domain’s registrar, registrant and status, whether a hostname is still seen. Alerts then describe what changed against it, instead of re-reporting the same exposure every run.
A Failed Source Is Not a Fix
A source that fails to answer proves nothing; services have outages. A subject is only recorded as gone when a source that did collect no longer reports it, which stops the inventory quietly closing real problems.
Alerts on What Changed
A new hostname under your domain, an address that now resolves to different names, a registration that changed hands: the alert names the change and the subject, so it is actionable rather than another report to skim.
Being Listed Is Not Permission to Test
Discovery suggests; authorization is separate, explicit and versioned. An asset appearing in the inventory is never a reason for anyone to start testing it.
Owners, Relationships and Lifecycle
Assets carry an owner, their relationships to other assets, and a lifecycle state. Retiring one keeps its history, and merging duplicates preserves the old identifiers and can be undone.
Feeds the Assessment Work
What discovery finds becomes the candidate scope for an assessment, so the question "what should we test this quarter?" is answered from the inventory rather than from memory.
Separation Between Organizations
Asset identity is scoped per organization, so two customers of the same provider registering the same hostname never see each other, and a service provider can run discovery for many clients from one installation.
Runs Where Your Data Has to Stay
Designed to be used as a service we operate, or installed inside your own network when an inventory of your exposure is itself sensitive, which for most organizations it is.

What It Sees

What public sources record about your organization: certificate transparency, passive DNS and registration data. Discovery is passive only and sends nothing to your systems; active checks are planned.

Domains and Subdomains
Hosts and IP Addresses
Domain Registrations
Certificates in Transparency Logs

Use Cases

Where nobody can answer what the organization actually runs

Organizations That Grew by Acquisition
Several IT departments, several conventions, no single list. Discovery proposes, your people decide, and one inventory comes out the other side.
Regulated Organizations
An auditor asks how you know this is the complete list of internet-facing systems. The answer is the record of decisions, not a screenshot of a tool.
Fast-Moving Engineering Teams
Environments appear on a Friday and nobody tells security. Change alerts name what is new on which asset, before someone else finds it first.
Supplier and Brand Exposure
Campaign sites, partner portals and systems carrying your name that you do not operate: visible, marked as third-party, and handled as the different problem they are.
Planning the Assessment Year
Deciding what to test next quarter from a maintained inventory with owners, rather than from whichever application shouted loudest.
Service Providers
Run discovery for many client organizations from one installation, with identities and decisions kept apart per client.

How It Works

From seed to action

1
Give It Seeds
Your domains, address ranges and organization names define where discovery looks. Campaigns can be scheduled or run when something changes.
2
Decide What Is Yours
Candidates arrive with their evidence and a confidence level. Your team accepts, rejects or marks them third-party, and every decision is recorded.
3
Watch for Change
Accepted assets get an observed baseline, and later observations are compared against it. Alerts describe the difference and who owns the asset it appeared on.
4
Act on It
Close the exposure, hand it to the owner, or turn it into the scope of an assessment — with authorization agreed separately, as it should be.

Ways to Use It

Operated by us, installed with you, or alongside assessment

Operated by Us
Planned: we run discovery and bring you the decisions to make, as part of a monitoring engagement.
Inside Your Network
Planned: install it where the inventory has to stay, and let your own team run campaigns and own the decisions.
Alongside Assessment
Planned: run it with VAaaS on one inventory, so what discovery finds is what the assessment plan is built from.

Why ASM

How it differs from running a discovery tool now and then

Finding Things Is the Easy Part
Any scanner returns thousands of candidates. Deciding which are yours, which belong to a supplier and which are noise is the work, and it is the part this product is designed around.
An Inventory You Can Defend
Every acceptance, rejection and retirement is recorded with its author and moment, so the list is a record of decisions rather than the output of the last scan.
It Does Not Close Problems Quietly
A source that is down, a run that returns nothing because of an outage: neither is treated as evidence that an exposure went away.
One List the Whole Programme Uses
The assets discovery accepts are the assets assessments are scoped against and findings are attached to. No reconciliation project, ever.
