Security Testing (VAPT) › OT/SCADA Security
OT/SCADA Security — Security testing that respects uptime and safety
OT and SCADA environments can't be tested like IT networks — an aggressive scan can crash a PLC or trip a safety system. SIRI Security assesses industrial control environments using passive and carefully-scoped active techniques built for that constraint.

Effective
31 JUL 2026
RBI's 2026 Framework requires commercial banks to run and evidence regular security testing as part of a continuous assurance programme, not a one-off exercise.
Named standard
OWASP TOP 10
Application and API testing scoped against the current OWASP Top 10 and OWASP ASVS remains the reference baseline auditors and regulators expect to see.
Growing gap
62% CLOUD
Cloud misconfiguration and IAM exploitation account for 62% of detections in cloud environments (DSCI) — testing scoped to on-premises infrastructure alone misses most of current risk.
Baseline
70% MALWARE
Trojans and file infectors make up 70% of malware detections (Seqrite 2026) — the entry point most exploitation testing has to account for.
Evidentiary bar
6 HR WINDOW
CERT-In's breach-notification window depends on already knowing your exposure — tested, documented findings are what makes that deadline realistic to meet.
Testing evidence, not a scan report
What is OT/SCADA Security assessment?
Operational technology security covers the industrial control systems, SCADA platforms, PLCs, and the IT/OT boundary that connects them to your corporate network — environments where an aggressive vulnerability scan can genuinely take a physical process offline or worse.
Our approach leans on passive network traffic analysis and configuration review first, with active testing scoped tightly and run in coordination with your operations team, aligned to IEC 62443. The IT/OT network boundary — where most real-world OT incidents actually originate — gets particular attention.
Scanners find the obvious; testers find what gets you breached
62% of cloud detections trace to misconfiguration and IAM exploitation (DSCI) — exactly the class of issue automated scanning alone tends to miss.
SIRI Security delivers OT/SCADA Security to this standard directly — practitioner-led, documented, and connected to SIRI Law LLP's legal and regulatory response if a finding ever needs to go further.
What organisations get wrong
Four assumptions that leave real exposure untested
A scanner report and a genuine security test are not the same evidence — and auditors increasingly know the difference.
01 — TOOLING
“We ran an automated scan, so we're covered”
Automated tools catch known signatures; they consistently miss business-logic flaws and chained vulnerabilities a human tester finds by thinking like an attacker.
02 — SCOPE
“Our last test covered the main system”
New features, integrations, and cloud services ship continuously — a test scoped a year ago doesn't speak to what's live today.
03 — EVIDENCE
“We fixed the findings, so we're done”
Without a documented retest, there's no evidence the fix actually worked — which is exactly what an auditor or insurer will ask for.
04 — FRAMING
“A clean report means we're secure”
A test result is a point-in-time statement about what was in scope — not a permanent guarantee, and not a substitute for ongoing monitoring.
What OT/SCADA Security covers
What's included, start to finish
Deployed once per engagement, documented to a standard auditors and insurers actually accept.
01
IT/OT boundary review
The segmentation and data-flow controls between your corporate network and the OT environment.
02
Passive traffic analysis
Protocol and asset discovery without risking disruption to live industrial processes.
03
PLC & HMI configuration review
Default credentials, unnecessary services, and unauthenticated protocols on control devices.
04
IEC 62443 gap assessment
Your OT security posture measured against the IEC 62443 zones-and-conduits model.
05
Scoped, coordinated active testing
Any active testing is scheduled with your operations team and scoped to avoid safety-critical systems.
Evidence, not guesswork
Unscoped internal effort vs. a documented SIRI engagement
The gap is rarely the tooling — it's whether the result holds up as evidence.
| Approach | No dedicated testing | Ad hoc internal effort | SIRI OT/SCADA Security |
|---|---|---|---|
| Methodology | None | Varies by who ran it | OWASP / CREST-aligned, documented |
| Manual exploitation | No | Rare | Included as standard |
| Evidence for auditors/insurers | None | Inconsistent | Formal report + CVSS ratings |
| Retest on fixes | N/A | Rarely tracked | One free retest cycle included |
| Satisfies RBI/SEBI testing expectations | No | Partially | Yes, when scoped to your entity category |

Numbers every board should know
What testing is actually catching
62%
Of cloud detections
Trace to misconfiguration and IAM exploitation (DSCI) — the category testing has to explicitly cover.
70%
Of malware detections
Are trojans and file infectors (Seqrite 2026) — the entry point most exploitation chains start from.
29.44L
Incidents CERT-In handled
In the latest reporting year — the scale of activity testing exists to reduce a share of.
6 HR
CERT-In notification window
Runs from discovery — tested, documented exposure is what makes that window realistic to meet.
Why SIRI for OT/SCADA Security specifically
Testing connected directly to legal and response, not a separate vendor
The same roof runs the test, the fix verification, and — if a real finding turns into an incident — the legal response.
01
Findings connected directly to legal exposure
SIRI Security runs under the same roof as SIRI Law LLP — when a finding carries real legal exposure, the engagement can be brought under attorney-client privilege from day one, not bolted on after the fact.
02
Led by named practitioners, not a rotating bench
Vikram Rao, SIRI's Head of Cybersecurity, directs offensive security and incident response and leads CERT-In breach containment for enterprise clients.
03
Court-admissible evidence when it matters
Ananya Krishnan, SIRI's Digital Forensics Lead, prepares court-admissible forensic reports and testifies as an expert witness when findings end up in front of a judge.
04
Built for RBI and SEBI's specific evidentiary bar
Testing is scoped and documented to the standard RBI's 2026 Framework and SEBI's CSCRF expect from regulated entities, not a generic vendor template.

PLC, HMI and SCADA configurations reviewed for default credentials, unnecessary services, and insecure protocols.
Weeks 2–303
IT/OT Boundary Testing
The segmentation between corporate IT and the OT floor, tested as the highest-value control in the environment.
Week 4+04
Reporting Against IEC 62443
Findings mapped to the IEC 62443 zones-and-conduits model with a prioritised, safety-aware remediation plan.
OngoingFrequently asked
OT/SCADA Security, answered directly
Will testing risk disrupting our operations?
We default to passive analysis and only run active tests where you and your operations team explicitly agree it's safe, scheduled around maintenance windows.
Do you work with our existing OT vendor?
Yes — we coordinate with your PLC/SCADA vendor and operations team throughout rather than testing in isolation.
Is this relevant if we're ISO 21434 or IEC 62443 scoped?
Yes, findings are mapped directly to IEC 62443 zones-and-conduits, and we also support ISO 21434 for automotive OT environments.
How long does an engagement take?
Most single-application or single-network engagements run 5 to 10 business days depending on scope, with the report and retest typically following within another week.
Close the evidence gap
Scope OT/SCADA Security.
Most engagements start with a short scoping call to confirm environment, timeline, and rules of engagement.
