Overview : Operational Technology Security
OT security safeguards the industrial control systems (ICS) and technologies that run critical infrastructure across manufacturing, energy, and transportation, protecting the devices, networks, and processes that control physical systems. It covers ICS, SCADA systems, PLCs, and HMIs, secured in line with IEC 62443 and NIST SP 800-82 Rev. 3.
- Exposes flat networks, weak IT/OT segmentation, unpatched legacy controllers, insecure remote access, and asset blind spots.
- Trusted by 1875+ enterprises and SMBs.
- OT Risk and Architectural Assessment: Asset, vulnerability, and threat rating, plus network design review and a prioritised remediation roadmap.

Our Approach
Information Gathering
Before we travel to the facility we will prepare for the on site visit by conducting document reviews, a Network Architecture, and discussions with your team. The goal is to familiarize ourselves with your product and develop a plan of action in advance. This preparation ensures we can make the most of our time onsite.
Planning
After gathering information, the next step involves planning and setting penetration testing objectives, agreed upon by both the tester and client. The pentester must fully understand the OT system, including its mission-critical components, functionalities, and end users. Key tasks include reviewing system documentation, researching products and vendors, and identifying known vulnerabilities and default credentials.
- Understanding the Network Layout
- Network Exploitation
- Planning Attacks
Vulnerability Detection & Exploitation
We will conduct a cybersecurity assessment and penetration test at your facility. Our assessment will identify all communication points in the OT system—such as Ethernet, Fiber, WiFi, USB, Serial Port, and HDMI—along with associated vulnerabilities and their exploitation. We will promptly inform you of any critical findings. For a thorough evaluation, we recommend executing each exploit individually during the security testing of OT networks or devices. This method helps identify the root causes of any unexpected failures. If an issue arises, we will immediately halt testing and notify you.
Reporting
The reporting phase is where pentest findings transform into action. Every vulnerability identified by Kratikal's security experts is documented, prioritized, and ranked within AutoSecT, giving stakeholders not just data, but a clear, evidence-backed, decision-ready roadmap. Findings are presented with full context, severity scoring, exploitability, and asset-level detail, so teams can interpret results instantly and align on what matters most. At Kratikal, reporting is treated as the most critical stage of the engagement; expert-led findings are delivered through AutoSecT, which also acts as a vulnerability management platform as a value-added service, so you know exactly where you stand and exactly what to do next.
AI-Based Patch Recommendations
AutoSecT's AI-based patch recommendations transform your remediation process by making it faster. For every vulnerability, the platform generates intelligent, context-aware remediation by analyzing the nature of the flaw, its potential business impact, and threat level. Rather than leaving developers to sift through generic advisories, AutoSecT also cuts through the noise. Its AI engine prioritizes vulnerabilities by real-world risk, helping teams resolve issues faster and far more efficiently than manual triage allows.
Re-Testing
The purpose of this assessment was to re-test all findings from the first round of penetration testing. During this re-testing, we provide updates on whether vulnerabilities are fixed, not fixed, or out of scope. The aim of this re-testing is to ensure that no vulnerabilities remain after the patching process, preventing attackers from exploiting any flaws in the application that could compromise your organization's security. The results from this round of re-testing will help the organization improve the security features of the medical devices. Significant findings from the assessment were communicated to management during or after the assessment, depending on the nature and risk level of each finding.
OT Risk Assessment and OT Architectural Assessment
Kratikal's OT security service rests on two complementary assessments. The first shows what could go wrong in your industrial environment and how much it matters. The second shows whether your network is designed to contain it.
OT Risk Assessment
Identifies and evaluates the cyber risks to your industrial control environment. We inventory your assets across ICS, SCADA systems, PLCs, and HMIs, map their vulnerabilities and the threats that apply to them, and rate each risk by likelihood and potential operational impact. Remediation then follows the risk to safety, availability, and production rather than a generic severity score. Our approach follows the logic of IEC 62443-3-2, which covers defining the system under consideration, partitioning it into zones and conduits, and assessing risk for each.
OT Architectural Assessment
Reviews how your OT network is designed, segmented, and connected. We examine how zones are separated, how traffic moves between IT and OT, and how remote and vendor access is controlled. The design is then evaluated against the ISA/IEC 62443 zone-and-conduit concepts, and NIST SP 800-82 Rev. 3. The outcome is a clear view of the design weaknesses that could let an attacker move from your corporate network towards your controllers, with recommendations to address them.
Together, the two assessments give security and plant teams a prioritised, evidence-backed roadmap to reduce OT risk.
