Client Success Story
ICS-Aware Penetration Testing for a Global Industrial IoT Provider
An IIoT provider serving 52,000+ customers and handling 39+ billion data readings ran on industrial control protocols that standard penetration tests routinely miss. InterSec built ICS-aware testing that surfaced critical vulnerabilities and cut major exploitable flaws by 90 percent.
The Challenge
Securing a large inventory of devices, many running specialized industrial control protocols, demanded an approach that went deeper than a typical penetration test. The intricacies of ICS channels are exactly what conventional scanning overlooks, and missing them could disrupt critical data flows.
The Approach
InterSec drew on deep ICS expertise to tailor the testing to these protocols rather than running a generic assessment. Three choices shaped the work.
The Solution in Practice
InterSec stood up a specialized testing lab that emulated real industrial conditions, so threats could be simulated accurately without putting production devices at risk. Within that environment the team probed hardware, firmware, and network flows for the weaknesses an attacker would look for, going past surface scanning into the components themselves. The engagement did not end at a findings list: InterSec delivered detailed remediation steps and ICS security practices, transferring the knowledge the client's teams needed to sustain the improvements.
Mirroring real industrial conditions in a lab let the testing go deep without risking the uptime customers depend on.
Results & Impact
The deep-dive approach surfaced critical vulnerabilities before they could be exploited, protecting the data streams that tens of thousands of customers rely on.
Key Takeaways
Working With InterSec
If your devices speak industrial protocols, a standard test misses what matters most.
InterSec builds ICS-aware testing that finds the flaws conventional scans pass over, then hands your team the fixes. Let's scope an engagement.
