Astelia
AI-native exposure management that finds and fixes the reachable 1% of vulnerabilities.
Astelia is a sharp overlay for enterprises drowning in vulnerability noise. It uses agentic AI to pinpoint the reachable 1% and delivers evidence that holds up in CISO conversations. Skip it if you lack existing VM tooling or want a standalone scanner—this is a context layer, not a replacement.

Skip Astelia if you don't already have a vulnerability management tool or network infrastructure integrations — it's a context overlay, not a standalone scanner, so without those pieces it has nothing to work with.
Pricing requires a sales call, so you may encounter custom quotes with minimum contract terms not visible upfront.
Astelia's pricing is contact-based, so you can't self-serve. It's built for enterprise budgets, not SMBs. Compare with VM tools like Qualys or Tenable that have published price lists, but those don't provide reachability context. Astelia's value is in cutting remediation costs by focusing on the 1%, which can offset its premium price for large enterprises.

About Astelia
Astelia is an AI-native exposure management platform for enterprise security teams overwhelmed by vulnerability noise. Instead of relying on CVSS scores alone, Astelia maps your network from the inside out using read-only integrations with your existing infrastructure and network tools. It then applies proprietary agentic AI to determine which vulnerabilities an attacker can actually reach, delivering evidence-based prioritization focused on the critical 1% of exposures that matter. The platform visualizes attack paths with graph-based representations, showing exactly how an attacker could traverse your network to compromise hosts. It also provides port-level visibility into third-party connections, VPN-accessible infrastructure, and unscanned assets buried in segmented networks—coverage gaps often missed by traditional tools. This inside-out mapping is designed for hybrid IT/OT environments where visibility is fragmented. The newly launched Astelia Agents (May 2026) automate the entire vulnerability lifecycle—detecting newly disclosed and zero-day vulnerabilities, assessing reachability, and coordinating fixes across security and IT teams. With 100+ MCP integrations, human-in-the-loop approvals, and full audit logging, these agents help you keep pace with AI-accelerated threats like Mythos, which Astelia partners with Anthropic to defend against. Astelia has earned the 2026 Fortress Cybersecurity Award and Gartner's recognition as a top-funded startup in preemptive exposure management. Astelia is an overlay layer that adds reachability context to your existing vulnerability management tooling—not a standalone scanner. It's best for enterprises that need defensible, evidence-based prioritization to align security and IT teams, as endorsed by CISOs from Syniverse, AlphaSense, and Bilfinger.
Behind the Verdict
Astelia addresses a real pain point: the vulnerability backlog is overwhelming, and most VM solutions cry wolf, labeling everything 'high risk' based on probability models. Astelia attacks this with a different approach—reachability. By mapping your network with read-only integrations and using agentic AI to extract the technical requirements for exploitation, it can tell you, with evidence, what an attacker can actually reach. This evidence-based prioritization is a game-changer for CISOs who need to justify remediation focus to boards and IT teams. The graph-based attack path visualization is particularly powerful—it shows exactly how an attacker could traverse your network, which is both a communication tool for executives and a tactical tool for remediation. The coverage gap detection, exposing third-party connections, VPN-accessible infrastructure, and unscanned assets, is another standout feature. For hybrid IT/OT environments, this visibility is often missing, and Astelia fills that gap. The 2026 addition of Astelia Agents is a significant step forward—automating the vulnerability lifecycle from detection to remediation, with human-in-the-loop approvals and audit logging. This addresses the speed of AI-accelerated threats like Mythos. The 100+ MCP integrations make these agents highly flexible. However, Astelia is not a standalone scanner; it relies on your existing VM tooling to feed it data. If you don't have that, it won't work. Pricing is contact-only, which is a hurdle for evaluation. There's no public API or CLI, which might limit automation for some teams. But for enterprises that already have a VM program and need to cut through the noise, Astelia is worth a serious look. It's not a replacement for your current tools—it's the brain on top.

Real-world workflow fit
Concrete scenarios for the personas Astelia actually fits — and what changes day-one when you adopt it.
A new zero-day vulnerability is disclosed, and your VM scanner flags it as critical across thousands of assets. Your team is overwhelmed.
Outcome: Astelia Agents automatically detect the vulnerability, assess reachability using your network map, and present a prioritized list of the few dozen assets that are actually exploitable. You approve the remediation steps, and the agents coordinate fixes across IT, cutting response time from weeks to days.
You have segmented networks with OT assets that are barely visible to your current tools. You suspect there are gaps but can't prove it.
Outcome: Astelia maps your network from the inside out, revealing third-party connections and VPN-accessible infrastructure that were previously missing. You see port-level detail and can now demonstrate coverage gaps to management, leading to improved security posture and reduced risk.
You spend hours triaging vulnerabilities, trying to decide which ones to patch first based on CVSS scores and gut feeling.
Outcome: Astelia shows you the attack paths and reachability for each vulnerability, so you can quickly focus on the handful that matter. You use the evidence to communicate with IT, who are more willing to patch when they see the actual network risk.
Use Cases
- Identify the 1% of vulnerabilities that are actually reachable in your environment, cutting through 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.

Limitations
- The platform relies on read-only integrations, so its effectiveness depends on the breadth of existing infrastructure tooling.
- Pricing is only available through sales contact, making it inaccessible for self-serve evaluation.
- All interaction is via the web UI with no publicly available API or CLI.

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's pricing is contact-based, so you can't self-serve. It's built for enterprise budgets, not SMBs. Compare with VM tools like Qualys or Tenable that have published price lists, but those don't provide reachability context. Astelia's value is in cutting remediation costs by focusing on the 1%, which can offset its premium price for large enterprises.
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.
Setup depends on your environment. Typical onboarding takes 2-4 weeks: week 1 for integration with your VM and network tools, week 2 for network mapping and baseline, weeks 3-4 for agent configuration and tuning. You'll see initial value once your first attack path visualizations are available, usually within the first couple of weeks.
