Astelia
AI-native exposure management that finds and fixes the reachable 1% of vulnerabilities attackers can actually exploit.
If your vulnerability backlog is measured in thousands and your IT team argues with security about what actually matters, Astelia's reachability evidence is the argument-ender. Named CISOs at Syniverse, AlphaSense and Bilfinger cite the network context directly. It won't replace your scanner — it's an overlay — and the 2026 Agents layer stretches it into full lifecycle automation with human-in-the-loop approvals. Skip it if you're small, scanner-free, or already have strong reachability context from current tools.

Skip Astelia if you have no existing vulnerability scanner or network infrastructure for it to read from — the reachability evidence it produces comes entirely from read-only integrations with those tools.
Because the platform is an overlay, value scales with integration breadth — every network or VM tool you run that Astelia cannot connect to is a blind spot you are paying for anyway.
Astelia is priced for enterprise security budgets — the named references are Syniverse, AlphaSense, Bilfinger and un-named Fortune 50 energy and Fortune 100 financial firms. Expect it to sit above lightweight reachability add-ons bundled into mid-market VM suites, and below full platform-security consolidation plays. The comparison that matters is not per-seat cost but the analyst hours you stop burning on unreachable findings.

About Astelia
Astelia is an AI-native exposure management platform for enterprise security teams buried under vulnerability backlogs that CVSS scores alone can't sort. Rather than ranking by probability models and external threat context, it maps your network from the inside out using read-only integrations with the infrastructure and network tools you already run, then applies proprietary agentic AI to extract each vulnerability's technical exploitation requirements and correlate them with actual reachability. The platform handles four core jobs: identifying true exposure, analyzing attack paths with graph-based representations, revealing coverage gaps down to the port level (third-party connections, VPN-accessible infrastructure, unscanned assets in segmented networks), and streamlining remediation with guidance beyond patching. In May 2026 Astelia launched Astelia Agents, which run the full vulnerability lifecycle — detecting newly disclosed and zero-day vulnerabilities, assessing reachability, and coordinating fixes across security and IT — drawing on 100+ MCP integrations with a human in the loop approving key decisions and every action logged and auditable. Astelia positions itself as an overlay that adds reachability context to whatever VM tooling you already run, not a standalone scanner. It suits hybrid IT/OT enterprises where visibility is fragmented and CISOs need defensible evidence for what they do and don't fix.
Behind the Verdict
Astelia attacks a real and specific problem: most vulnerability management programs rank by CVSS or probability models and external threat feeds, which is exactly why security teams end up with thousands of "high risk" findings that nobody can act on. Astelia inverts the approach. It maps your network from the inside out using read-only integrations with the infrastructure and network tools you already run, then applies proprietary agentic AI to extract the technical requirements for exploiting each vulnerability and correlates those against what is actually reachable from where an attacker could stand. The output is the 1% that matters, with evidence attached. The four core use cases are well-differentiated. Identify true exposure correlates reachability and exploitability layers. Analyze attack paths renders graph-based representations of how an attacker could traverse your network to reach specific hosts. Reveal coverage gaps maps down to the port level and surfaces third-party connections, VPN-accessible infrastructure, and unscanned assets buried in segmented networks — the class of asset most scanners simply never see. Streamline remediation goes past patching to network-based and compensating controls you can apply without taking production down, which is often the difference between a ticket that closes and one that sits open for a quarter. The May 2026 launch of Astelia Agents is the biggest shift. Agents now run the entire vulnerability lifecycle — detecting newly disclosed and zero-day vulnerabilities, assessing reachability, and coordinating fixes across security and IT — drawing on 100+ MCP integrations. Human-in-the-loop approval gates the key decisions and every action is logged and auditable. That loop is aimed squarely at AI-accelerated threats like Mythos that exploit at machine speed, where a human triage queue is a losing position. Where it fits: hybrid IT/OT enterprises where visibility is fragmented across segmented networks, and CISOs who need to defend in writing why they did — and didn't — fix something. The customer roster quotes CISOs at Syniverse, AlphaSense, Bilfinger and un-named Fortune 50 energy and Fortune 100 financial firms, which matches the segmentation-heavy profile. Where it doesn't: small teams without existing network infrastructure or VM tooling to enrich, because network mapping depends entirely on the breadth of those read-only integrations. Organizations still buying on raw CVSS scores won't get value from an overlay that exists to contradict them. Teams shopping for a standalone scanner are in the wrong aisle — Astelia is context, not detection. And mature VM programs that already have strong reachability signal from their current stack won't find enough new here to justify a second platform. The clearest constraint is that the value scales with integration breadth: every tool you can't connect is a blind spot in the map.

Real-world workflow fit
Concrete scenarios for the personas Astelia actually fits — and what changes day-one when you adopt it.
Deploy read-only integrations into existing network and infrastructure tooling so Astelia can map the environment from the inside out, then correlate each open vulnerability's exploitation requirements against what is actually reachable.
Outcome: A defensible, evidence-backed shortlist of the reachable 1%, usable in writing to justify to the board and to IT exactly what will and will not be fixed.
Run analysis on a host flagged critical to see the graph-based attack path showing whether an attacker could actually traverse the network to reach it, then apply Astelia's remediation guidance for compensating controls instead of an outage-window patch.
Outcome: The finding gets closed with a network-based control the same week instead of sitting open pending a maintenance window.
Turn on Astelia Agents to detect newly disclosed and zero-day vulnerabilities, assess their reachability, and coordinate fixes across security and IT — with a human approving the key decisions and every action written to the audit log.
Outcome: Machine-speed exploitation is met with an automated lifecycle loop that still leaves an auditable, human-approved trail.
Use Cases
- Identify the 1% of vulnerabilities that are actually reachable in your environment, cutting through the noise.
- Visualize attack paths showing exactly how an attacker could traverse your network and compromise hosts.
- Reveal coverage gaps by mapping third-party connections, VPNs, and internet-facing systems often missed.
- Streamline remediation with guidance beyond patching, including network-level and compensating controls.
- Align security and IT teams around evidence-driven risk priorities, reducing friction and accelerating fixes.
- Automate the vulnerability lifecycle with Astelia Agents so machine-speed exploits meet machine-speed response.
Models Under the Hood
as of 2026-10-16
Limitations
- Effectiveness depends on the breadth of existing infrastructure tooling, since the inside-out network map is built entirely from read-only integrations — every tool you cannot connect is a blind spot.
- Public customer references (Syniverse, AlphaSense, Bilfinger) skew large-enterprise.
- The Astelia Agents layer relies on human-in-the-loop approval for key decisions, which means someone still has to be in the chair.

Where the pricing makes sense
The company stage and team size where Astelia's pricing actually pencils out — and where peers do it cheaper.
Astelia is priced for enterprise security budgets — the named references are Syniverse, AlphaSense, Bilfinger and un-named Fortune 50 energy and Fortune 100 financial firms. Expect it to sit above lightweight reachability add-ons bundled into mid-market VM suites, and below full platform-security consolidation plays. The comparison that matters is not per-seat cost but the analyst hours you stop burning on unreachable findings.
Setup time & first value
How long it actually takes to get something useful out of Astelia — broken out by persona, not the marketing-page minute.
For enterprises with existing network and VM tooling: the first inside-out network map depends on how many read-only integrations you connect, so budget an integration sprint before the first reachability report. For CISO stakeholders: the strategy value (a defensible "reachable 1%" list) follows the first completed analysis cycle, not day one. For security engineers: attack-path views and
Switching to or from Astelia
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From CVSS-only scoring in an incumbent VM platform: add Astelia as a reachability overlay and re-rank the backlog against actual exposure.
- →From probability-based risk models with external threat feeds: replace the ranking layer while keeping your existing scanner for detection.
- →From manual spreadsheet triage of open vulnerability tickets: feed the mapped topology in and let Astelia produce the prioritized shortlist.
- →From patching-only remediation queues: adopt compensating and network-based control guidance to close findings that can't wait for a maintenance window.
- ↗To a consolidated platform-security suite: Astelia's reachability context would have to be replaced by whatever exposure module the suite ships.
- ↗To a standalone network scanner with built-in reachability: you would lose the overlay model that lets Astelia sit across heterogeneous existing tooling.
