AI-native exposure management that proves which vulnerabilities an attacker can actually reach, then drives the fix
Astelia is an AI-native exposure management platform that maps real network topology and correlates it with exploitation requirements to determine which vulnerabilities are genuinely reachable. It is built for security teams buried in scanner output: in one enterprise deployment it cut roughly 40 million findings down to fewer than 2,000 that presented real exposure.
Astelia is an exposure management platform founded in 2024 by former leaders of the Israeli National Red Team - Alon Noy (CEO), Nadav Ostrovsky (CTO) and Roy Rajwan (CPO) - and headquartered in New York. Its premise is that vulnerability counts are the wrong unit of work: the company reports that under 1 percent of scanner findings present real exposure, and that in one enterprise deployment approximately 40 million identified vulnerabilities reduced to fewer than 2,000 genuinely reachable ones. The platform builds a model of the customer's actual infrastructure using read-only integrations with existing infrastructure and network tooling, then runs reachability analysis that correlates network topology against the technical preconditions an exploit requires. That produces attack-path visualization, coverage-gap identification for unscanned assets and misconfigurations, and remediation guidance that extends beyond patching to network segmentation, configuration changes and compensating controls. On July 22, 2026, timed to Black Hat USA, Astelia extended this with an agentic AI layer that runs the whole vulnerability lifecycle: it evaluates newly disclosed and zero-day vulnerabilities, assesses reachability and operational impact, coordinates remediation across security and IT teams, and drives each issue toward resolution. Human approval remains built into key decision points, with every action logged and auditable, and the agents reach into more than 100 MCP-enabled systems. The company raised $35 million in combined seed and Series A funding in February 2026, led by Index Ventures and Team8 with Holly Ventures participating, and is SOC 2 and ISO 27001 certified.
Vulnerability management and security operations leads at large enterprises whose scanners produce millions of findings and whose patch backlog is growing faster than the team can close it.
A defensible, evidence-backed shortlist of the vulnerabilities an attacker can actually reach, with the fastest remediation path attached - one Fortune 100 financial CISO reports triage time cut by over 80 percent.

Key Features
- ✓Reachability analysis
Correlates real network topology with each exploit's technical preconditions to prove whether an attacker could actually reach the flaw.
- ✓Read-only infrastructure mapping
Builds the network model through read-only integrations with existing infrastructure and network tools, avoiding agents on production hosts.
- ✓Agentic vulnerability lifecycle
Autonomous agents evaluate new disclosures, assess operational impact, coordinate cross-team remediation and push each issue toward closure.
- ✓Attack-path visualization
Shows how an attacker would traverse the environment, turning a list of CVEs into a defensible narrative for leadership.
- ✓Remediation beyond patching
Recommends the fastest evidence-based fix, which may be segmentation, a configuration change or a compensating control rather than a patch.
- ✓Coverage-gap identification
Surfaces unscanned assets and misconfigurations the existing scanning program never reported, closing blind spots in inventory.
- ✓100+ MCP integrations with audit trail
Agents act across MCP-enabled systems with human approval at key decision points and every action logged for audit.
Capabilities
Use Cases
- •Cutting a multi-million-finding backlog to a workable list
One enterprise deployment reduced roughly 40 million identified vulnerabilities to fewer than 2,000 that were actually reachable in their environment.
- •Zero-day triage at disclosure
When a new CVE lands, agents assess reachability and operational impact immediately rather than waiting on a manual assessment cycle.
- •Defending deprioritization to auditors and boards
Evidence-based reachability reasoning is logged and auditable, so a deprioritized critical-severity CVE has a documented justification behind it.
- •OT and industrial environments where patching is disruptive
Recommends network segmentation and compensating controls when taking a production system offline for a patch is not viable.
- •Cross-team remediation coordination
Agents route work between security and IT teams and drive each issue toward resolution instead of leaving tickets to age.
Ideal For
Best For
- ✓Enterprises drowning in scanner output from Tenable, Qualys or Rapid7 that need reachability evidence to defend a shortened patch list
- ✓Security teams responding to newly disclosed and zero-day vulnerabilities who need a reachability verdict at machine speed rather than in days
- ✓Organizations with mixed IT and OT estates where blanket patching is operationally impossible and compensating controls matter
- ✓Programs that must show auditors why a critical-rated CVE was deprioritized, using logged and evidence-based reasoning
- ✓Teams standardizing on MCP who want exposure workflows to reach into the ticketing and infrastructure systems they already run
Not Ideal For
- ✗Buyers who require published list pricing - Astelia publishes none, and procurement runs through direct sales or AWS Marketplace
- ✗Small and mid-sized organizations whose scanner output is already tractable, where reachability analysis solves a problem they do not have
- ✗Teams that want a scanner - Astelia consumes findings from existing tools through read-only integrations rather than replacing them
- ✗Risk-averse buyers who need a long production track record; the company was founded in 2024 and has no independent user reviews on G2, Capterra, TrustRadius or Hacker News
- ✗Organizations expecting fully autonomous remediation, since human approval is deliberately retained at key decision points

Market Analysis
Pros
- ✓Reachability analysis produces a dramatically smaller and defensible work list - roughly 40 million findings to under 2,000 in one deployment, with under 1 percent of findings presenting real exposure
- ✓A Fortune 100 financial CISO quoted in the launch release reports triage time cut by over 80 percent
- ✓Remediation guidance extends past patching to segmentation and compensating controls, which matters in OT and change-controlled environments
- ✓SOC 2 and ISO 27001 certified, and read-only integrations lower the deployment risk of adding it to an existing program
- ✓Backed by $35M from Index Ventures and Team8, with named enterprise customers including Syniverse, AlphaSense, Bilfinger and UCT
Cons
- ✗No independent user reviews exist - G2, Capterra, TrustRadius and Hacker News all return nothing on Astelia, so every quality signal available today is vendor-supplied or analyst-relayed
- ✗The headline numbers (40 million to under 2,000 findings, 80 percent triage reduction, under 1 percent real exposure) are vendor-reported from unnamed deployments and have not been independently audited
- ✗No published pricing at all, so buyers cannot size the spend before entering a sales cycle
- ✗Founded in 2024, so there is a short production track record relative to Tenable, Qualys and Rapid7 incumbents it sits alongside
- ✗Output quality is bounded by the accuracy of the scanner, CMDB and network data it reads - an incomplete asset inventory produces incomplete reachability
- ✗Exposure management is a crowded and rapidly funding market (Cogent Security, Nucleus, Brinqa and the incumbents all ship comparable prioritization), so differentiation rests on reachability evidence that is hard to evaluate without a bake-off
Pricing
Enterprise
Contact for pricing
- ✓Reachability analysis and attack-path visualization
- ✓Agentic vulnerability lifecycle automation
- ✓100+ MCP integrations
- ✓Read-only infrastructure integrations
- ✓Available via AWS Marketplace
Astelia publishes no list pricing anywhere on its site; every path runs through a sales conversation or an AWS Marketplace private offer, so the metering unit - assets, findings ingested or scanner connections - is not public either. Nothing in the February 2026 funding coverage or the July 2026 launch materials discloses a starting price or contract minimum. Budget for a direct enterprise negotiation and expect a proof of value against your own scanner output, since the platform's whole claim is environment-specific reachability that cannot be demonstrated on generic data.
