FAQs
Will segmentation testing disrupt my operations?
No. Testing is carefully scoped, coordinated with IT/OT teams, and conducted under strict safety controls.
Do I need segmentation testing if I already have firewalls?
Yes. Firewalls alone don’t guarantee isolation — segmentation testing validates whether boundaries truly prevent unauthorized access.
How often should OT segmentation be tested?
Regularly. Continuous monitoring, audits, and periodic retesting ensure controls remain effective against evolving threats.
