Horizon3.ai NodeZero pricing and features

  1. 1

    Aikido

    Aikido is a developer security platform that scans code, dependencies, secrets, and cloud, and runs agents that detect issues, open fix pull requests, deploy to staging, and verify the fix. Its Attack product autonomously attacks running applications, APIs, and infrastructure to prove what is exploitable.

    Pricing: Free. Best for: Engineering teams that want AppSec findings turned into pull requests, plus proof of what is exploitable.

  2. 2

    Dropzone AI

    Dropzone AI is an agentic SOC platform whose AI SOC Analyst investigates alerts across the existing tool stack and whose AI Threat Hunter runs hypothesis-driven hunts. The site says it ships with 90-plus integrations across SIEM, EDR, cloud, identity, and email, and that analysts set strategy and authorize containment.

    Pricing: Not published. Best for: SOC teams that want machine-scale alert investigation and hunting without replacing analysts.

  3. 3

    Intezer

    Intezer's AI SOC triages, investigates, and can respond to alerts, including low-severity ones, using endpoint forensics, memory analysis, and reverse engineering alongside AI models. The site says it resolves more than 98 percent of false positives in under a minute and prices by endpoint rather than by alert volume.

    Pricing: Not published. Best for: Enterprise SOCs that want forensic triage of the full alert queue.

  4. 4

    Pentera

    Pentera is an exposure-validation platform that emulates real attacks in live production, prioritizes what is exploitable, and can orchestrate remediation and retest the fix. It says it covers internal networks, external assets, cloud, and hybrid environments and supports all five stages of continuous threat exposure management.

    Pricing: Not published. Best for: Enterprises that want validated attack paths and a retest after remediation.

  5. 5

    Prophet Security

    Prophet AI investigates alerts, hunts threats, and ships tuned or new detections that are backtested for approval. Response can run through scoped agent actions autonomously or with a sign-off, and a human Watchtower reviews malicious determinations around the clock.

    Pricing: Not published. Best for: SOCs that want every alert investigated and still want a human check on malicious verdicts.

  6. 6

    RunSybil

    RunSybil is an AI offensive-security platform that tests applications and infrastructure by reasoning about the system the way a human researcher would, on every deployment. It says it covers code, APIs, cloud, and infrastructure, including business-logic and multi-tenant issues, and that it validates whether exposures are actually exploitable.

    Pricing: Not published. Best for: Product teams that want pentest-style findings on each deployment instead of an annual test.

  7. 7

    Torq

    Torq's AI SOC platform triages events, investigates cases with specialized agents, and can respond either autonomously or with a human in the loop. Its Socrates agent is described as natural-language agentic AI that remediates critical threats, and every decision is written to a context model with an audit trail.

    Pricing: Not published. Best for: Security operations teams that want agentic response with an override still available.

    Also listed for Best AI Pentesting Tools.

  8. 8

    XBOW

    XBOW is an autonomous offensive security platform that explores applications and APIs, chains vulnerabilities into working attacks, and proves exploitability before a finding reaches the team. The company says more than 150 security teams use it, and that it was the first autonomous system to rank number one on HackerOne in June 2025.

    Pricing: Not published. Best for: Security teams that want continuous, proof-of-exploit testing of web apps and APIs.
