MITIGATOR Cyber Risk and Threat Intelligence Platform

Powered by Mitigator™

Most penetration test findings live and die in a PDF - read once, filed away, stale the moment the ink dries. InfoSight's don't. Every AI Penetration Testing engagement runs through Mitigator, InfoSight's proprietary threat-intelligence dashboard, and stays there for as long as you're a client.

  • A live portal, not a static report - see current AI risk posture any time, no waiting on the next PDF.
  • Remediation tracking, not a findings list - every finding carries a status: open, in progress, validated closed.
  • Trending over time, not a snapshot - see whether AI risk is going up or down release over release.
  • Board-ready views on demand - pull a current risk summary ahead of a board meeting or audit.
  • Exposure mapped to your frameworks - NIST AI RMF, OWASP Top 10 for LLMs, HIPAA, PCI DSS, GLBA - updated as findings are remediated.

Illinois - Penetration Testing Frequently Asked Questions

Because Illinois is home to financial services, manufacturing, and retail organizations that manage sensitive data and critical operations, penetration testing provides clear, evidence-based insight into how an attacker could compromise your systems, allowing you to prioritize remediation where it matters most.

Penetration testing helps Illinois organizations in financial services, manufacturing, and retail demonstrate alignment with frameworks such as GLBA and PCI DSS, providing the documented evidence many auditors and regulators require to validate security controls.

Yes. Many Illinois organizations in financial services, manufacturing, and retail rely on cloud platforms and custom applications, so assessments cover cloud configurations, APIs, and application logic in addition to traditional network infrastructure.

Annual testing is the minimum recommended cadence for most Illinois organizations, but financial services businesses that handle sensitive data or face frequent system changes often benefit from more frequent assessments.

Engagement length varies with scope, but most Illinois penetration tests take one to three weeks from kickoff to final report, depending on the size and complexity of the financial services environment being tested.
