Which tool scores higher on each criterion?
| Criterion | Hadrian | watchTowr | Higher |
|---|---|---|---|
Finds the unlisted estate 15%WhyHadrian: Scans hourly or on events to keep the external inventory current; subsidiary mapping is not documented. watchTowr: Maps the external estate including subsidiaries, brands and acquired companies, with zero install. | 7 / 10 | 8 / 10 | watchTowr |
Routes to an owner 10%WhyHadrian: Machine learning confirms whether an asset belongs to the organization. watchTowr: Maps assets to subsidiaries, brands and M&A; the evidence behind each attribution is described only briefly. | 7 / 10 | 7 / 10 | Tie |
Proves exploitability 20%WhyHadrian: Agentic AI exploits issues to prove impact; Hadrian states it proves exploitability within 15 minutes. watchTowr: Eight automated red-teaming agents, from web applications to credential stuffing and DNS, and Project Red reproduces emerging vulnerabilities to validate exposure. | 9 / 10 | 9 / 10 | Tie |
Contains before the patch 20%WhyHadrian: No edge rule, playbook or other compensating control is described. watchTowr: Active Defense pushes ready-to-use rules to existing WAFs, firewalls, IPS and IDS, naming Cloudflare, Akamai, Imperva, F5, Fortinet, Check Point and Citrix. | 2 / 10 | 8 / 10 | watchTowr |
Closes the loop 15%WhyHadrian: Remediation guidance, automatic tickets and automatic regression testing after a fix. watchTowr: Creates work in eight named ticketing tools and re-tests the hour a threat emerges; a retest after your own fix is not described separately. | 9 / 10 | 7 / 10 | Hadrian |
Fits the enterprise stack 10%WhyHadrian: Names Jira, ServiceNow, GLPI, Slack, Microsoft Teams, SentinelOne, Datadog, Zendesk and HubSpot plus an API. watchTowr: Eight ticketing and workflow connections and seven edge vendors; SIEM connections are not named on the pages reviewed. | 6 / 10 | 7 / 10 | watchTowr |
Buying transparency 10%WhyHadrian: NOVA pentests from 1,250 euros per test excluding VAT, and ATLAS on AWS Marketplace at $50,000 per 12 months for up to 250 assets. watchTowr: No pricing published. | 7 / 10 | 2 / 10 | Hadrian |
