Frequently asked questions

What is the best alternative to Hadrian?

On our default weights it is IONIX at 8.05. If Hadrian's weakest criterion, contains before the patch, matters most to you, IONIX scores highest there (9/10).

Is there a cheaper alternative to Hadrian?

Few tools here publish prices. IONIX: AWS Marketplace, 1-month contract, cost per month: Silver Plan (monthly monitoring) $25,000; Gold Plan (weekly monitoring) $35,000; Platinum Plan (continuous monitoring) $45,000. CyCognito: Pricing basis published: total asset volume for ASM; active IPs and web applications for exposure validation. Cortex Xpanse: No price from Palo Alto Networks. Tenable ASM: ASM: quote only. Microsoft Defender EASM: Billed through Azure on billable assets (approved host:IP combinations, domains and IP addresses) after a 30-day free trial. The rest publish no price.

Which alternative to Hadrian contains exposures before the patch?

IONIX: Agentic mitigation invokes compensating controls: WAF rules within the 12-hour SLA; Active Protection reclaims hijackable assets. watchTowr: Active Defense pushes rules to seven named edge vendors. Cortex Xpanse: Active Response automated playbooks.
