Background

Astelia was founded in 2024 by former leaders of the Israeli National Red Team. They built it on an attacker-first approach: the question that matters is not how severe a vulnerability is, but whether an attacker can actually reach it.

Frontier AI models can now turn a published CVE into a working exploit in hours. Security teams cannot deprioritize findings by CVSS, severity or presumed exploitability anymore, and they are buried under millions of "critical" findings they cannot fix in time.

Astelia replaces that guesswork with proof. Its reachability analysis maps real network topology and identifies the ~1% of vulnerabilities that are reachable and exploitable in a specific environment. Astelia does not stop at prioritization: it eliminates reachable vulnerabilities through remediation and network mitigation, closing attack paths even when a patch is not available. Astelia is an AI-native exposure management platform for large enterprises running complex on-prem, hybrid and cloud networks.

Core Products and Solutions

Astelia is a single AI-native exposure management platform. It sits on top of the vulnerability scanners an organization already runs and takes teams from prioritizing reachable vulnerabilities to eliminating them, across these use cases:

• Identify True Exposure: Astelia correlates each vulnerability's exploit requirements with the live network topology. It separates the ~1% of vulnerabilities an attacker can reach from the ~99% they cannot, and gives evidence for each verdict. Built for vulnerability management teams that need a defensible, short list of what to fix first.
• Analyze Attack Paths: Graph-based attack path visualization shows exactly how an attacker could move from an entry point to a vulnerable asset, down to the port level. Security architects and red team leads use it to prove lateral movement risk to leadership and auditors.
• Reveal Coverage Gaps: Astelia builds a live inventory of assets and how they connect across on-prem, hybrid and cloud environments. It exposes assets and network segments that existing security tools do not see or do not scan.
• Streamline Remediation: Astelia eliminates reachable vulnerabilities, not just ranks them. For each one, it drives the fastest effective fix: a patch, or a network mitigation such as a firewall or configuration change, segmentation or a compensating control that closes the attack path. Security and IT teams get one evidence-based plan, including for systems that cannot be patched in time.
• Astelia Agents: A coordinated set of AI agents runs the exposure lifecycle at scale, from ingesting new CVEs and analyzing reachability to routing ownership and driving remediation. Humans approve key decisions, and every action is logged and auditable. Built for lean security teams that need to keep pace with AI-driven threats.

Data Sources and Coverage

Astelia builds its network model from read-only integrations with the infrastructure an organization already runs. These include firewalls (such as Palo Alto Networks, Check Point and Fortinet), load balancers and WAFs, and vulnerability scanners (such as Tenable, Qualys and Rapid7). It also draws on asset, CMDB, identity and endpoint data. Astelia enriches this with exploit and threat intelligence, including CISA KEV, NVD, vendor and GitHub advisories, public proof-of-concept exploits and EPSS. Astelia Agents connect to the wider enterprise stack, including ticketing, knowledge bases and communication tools, through 100+ MCP integrations.

Key Features and Capabilities

• Reachability analysis: Determines whether each vulnerability can actually be reached in your network, based on real topology, firewall policy and port-level access. The result is a yes-or-no answer backed by evidence, not another risk score.
• Agentic AI exploitability analysis: AI agents extract the technical requirements of each exploit (network path, services, configuration, privileges) and check them against your environment.
• Network topology mapping: A continuously updated map of assets, connections and policies, built through read-only integrations.
• Attack path visualization: Graph-based views of every path an attacker could take to a reachable vulnerability.
• Remediation and network mitigation: Eliminates reachable vulnerabilities through patching or network mitigation, including firewall and configuration changes, segmentation and compensating controls.
• Zero-day and new CVE detection: Matches newly disclosed vulnerabilities against your software inventory before the next scanner cycle.
• Integrations and MCP: 100+ MCP integrations let Astelia Agents work inside existing ticketing, CMDB, patch management and communication tools.
• Human-in-the-loop governance: Approval queues, role-based access control, and full audit and execution logs for every agentic action.
• Auditor-ready evidence: Every deprioritized finding comes with the network evidence explaining why it is not reachable.

Industries and Use Cases

Astelia is built for organizations whose critical workloads run in large on-prem and hybrid environments:

• Telecommunications: Prioritizing vulnerabilities across large, segmented carrier and data center networks.
• Energy, utilities and oil & gas: Protecting IT and OT systems that cannot be patched on normal schedules.
• Financial services: Giving auditors and regulators evidence for what was patched and what was safely deprioritized.
• Airlines, travel and hospitality: Securing complex reservation, operations and data center estates.
• Retail: Covering stores, distribution centers and logistics networks.
• Manufacturing and industrial: Protecting plants and legacy systems that require compensating controls.
• Healthcare and pharmaceuticals: Securing hybrid environments with legacy clinical and manufacturing systems.

Common use cases include vulnerability backlog reduction, remediation prioritization, vulnerability elimination through network mitigation, attack path analysis, compensating controls for unpatchable systems, audit and board reporting, and aligning security and IT on a shared remediation plan.

Competitive Differentiators

• Reachability as proof, not probability: Astelia answers whether a vulnerability is reachable in your environment with network evidence, instead of ranking findings by CVSS, EPSS or a generic risk score.
• Network topology fidelity: Astelia maps how assets actually connect at the network layer, down to the port, across on-prem, hybrid and cloud environments.
• Attacker-first DNA: Founded by former leaders of the Israeli National Red Team, Astelia analyzes vulnerabilities the way an attacker would.
• Remediation and network mitigation: Astelia does not stop at prioritization. It eliminates reachable vulnerabilities through remediation and network mitigation, and when a patch does not exist or cannot ship in time, it drives the network changes and compensating controls that close the attack path.
• Built on what you already own: Read-only integrations sit on top of existing scanners, firewalls and IT tools. No rip-and-replace.
• Agentic AI with human control: AI agents work at machine speed, while humans approve key decisions and every action stays auditable.

Astelia Is Ideal For

• Company types: Large enterprises, typically 4,000+ employees, with significant on-prem data center footprints and hybrid architectures, often in regulated industries.
