Case Study: City of St. Petersburg achieves a 45% reduction in vulnerabilities across 3,000 hosts with Horizon3.ai's NodeZero

How NodeZero Helped the City of St. Petersburg Improve Its Defenses

The City of St. Petersburg engaged Horizon3.ai after a chance phone call to find ways to improve an already streamlined security program. Their IT Security Officer evaluated Horizon3.ai’s NodeZero in a test lab, confirming the autonomous penetration testing product could locate hard-to-find artifacts and augment existing pentesting workflows.

Horizon3.ai implemented NodeZero’s continuous autonomous penetration testing to expand coverage and speed assessments, with a collaborative vendor team that adapted features to the city’s needs. The result: a 45% reduction in identified weaknesses across roughly 3,000 internal hosts, faster testing cycles, and measurable time savings for the city’s security team.
