Offensive Security & VAPT
IoT & OT/ICS Security
Operational technology and connected devices were rarely designed for internet-era threats. We assess IoT devices and OT/ICS environments - firmware, protocols, segmentation and physical interfaces - with a safety-first methodology.
Typical timeline
8–12 business days
Engagement model
Grey / black / white box
How it runs
Kickoff → test → report → re-test
Overview
Operational Technology (OT/SCADA) and connected IoT devices require specialized, safety-conscious auditing. Standard active network scanners can easily crash critical PLCs and ICS devices.
Our safety-first OT security assessments audit firmware, hardware interfaces, industrial protocol segmentation (Modbus, BACnet), and device-to-cloud communications without interrupting production.
At a glance
- Firmware and hardware interface analysis
- Industrial protocol and segmentation testing
- Device and cloud/companion-app review
- Safety-conscious OT methodology

Why A5
Why teams pick us
Manual-first, not scan-first
Senior testers hand-craft test cases for your business logic - scanners only set the baseline.
Proof, not guesses
Every finding ships with a working proof-of-concept and exact reproduction steps.
Fix-focused reporting
Remediation with code and config examples, not just a CVSS number and a shrug.
Re-test included
We verify your fixes and issue a clean report - closure, not just discovery.
FAQ
Frequently asked
Is OT testing safe for production?
We use a safety-first methodology, prefer test/lab environments, and agree strict limits before any production interaction.
