Security / OT Security

ANSOL covers IT and OT security simultaneously — vulnerability assessment, penetration testing, SOC/SIEM, security consulting and OT/ICS security, from assessment through to improvement.

ANSOL's Security Approach

Separate reports for management summary and technical team detail

Risk prioritization based on business impact, not just severity scores

Integrated security view covering IT and OT without treating them separately

End-to-end support through improvement and re-assessment after evaluation

Common Security Challenges

globe

Web and API risks

Inadequate handling of OWASP Top 10 web/API vulnerabilities, authentication flaws and data exposure risks.

🔀

Poor IT/OT separation

Insufficient network segmentation between IT and OT environments, creating risk that IT-side breaches spread to control systems.

shieldCheck

Misconfiguration and access control gaps

Cloud and on-premises misconfigurations, excessive permissions and weak management account security are common.

clipboard

Lack of security governance

Policies, procedures and incident response plans either do not exist or have become formalities disconnected from actual operations.

Why security improvement often stalls

Assessment completed but improvement stalled

Many teams receive a diagnostic report but cannot determine priorities, leaving remediation stuck.

IT-centric approach applied to OT without adaptation

Applying IT security approaches directly to OT environments increases availability and safety risks.

No risk prioritization framework

Treating all findings equally by severity score without mapping to business impact.

No continuous improvement cycle

Annual-only assessments with no continuous monitoring, re-assessment or improvement cadence.

How We Work

Scoping & Principles

Clarify assessment scope and goals

Define target systems, environment, business goals, constraints and OT environment safety requirements. Agree on methodology, depth and reporting format upfront.

Survey & Assessment

Evaluate security status and identify risks

Conduct vulnerability assessment, penetration testing, configuration review and log analysis, then classify risks by business impact order.

Improvement Plan & Validation

Build roadmap and execute improvements

Present a prioritized improvement roadmap, support remediation implementation and confirm effectiveness through re-assessment.

Why Businesses Choose ANSOL

🔭

IT and OT integrated security view

ANSOL evaluates risks with an integrated view of IT and OT without treating them separately, including attack paths to control systems from the IT side.

shield

Safe assessment methodology for OT environments

SCADA, PLC and ICS environments prioritize availability and physical safety. ANSOL uses non-disruptive assessment approaches that do not affect operations.

📐

International standards alignment

ANSOL delivers assessment, design and improvement plans based on IEC 62443, NIST, ISO 27001, OWASP and PTES.

refresh

End-to-end support from assessment to improvement

ANSOL does not stop at delivering a diagnostic report. We support prioritization, remediation, re-assessment and continuous monitoring.

FAQ

What is the difference between OT security and IT security?
OT security targets industrial control systems (SCADA, PLC, ICS) and prioritizes availability, physical safety and continuous operation above all. Directly applying IT security methods to OT environments can risk disrupting operations. ANSOL has expertise in both and selects appropriate methodologies.
What types of businesses is this suitable for?
ANSOL serves businesses with OT environments such as manufacturing, logistics, utilities, automotive and pharma, as well as businesses requiring high information security such as web services, cloud and financial services.
Can OT environment assessment be conducted without stopping operations?
Yes. OT environment diagnostics use non-disruptive methodologies that assume continuous process operation. ANSOL primarily uses scan configuration review, network traffic analysis and log analysis without direct intervention in systems.
Can penetration testing be done on live OT/SCADA systems?
Active penetration testing on live OT/SCADA is generally not conducted due to the risk of disruption. Instead, ANSOL recommends passive assessment, configuration review, protocol analysis and testing in test environments.
Which international standards and frameworks does ANSOL support?
ANSOL delivers assessment and improvement plans based on IEC 62443 (OT), NIST CSF, ISO 27001, OWASP, PTES and CVSS. Frameworks are adjusted according to compliance requirements.
Can ANSOL support improvement after the assessment?
Yes. ANSOL handles the full cycle after assessment: improvement roadmap development, priority remediation support, re-assessment and continuous monitoring.
What is the use case for TXOne Element?
TXOne Element is a lightweight security agent for OT/ICS environments, effective for protecting legacy systems and equipment with non-upgradeable operating systems. ANSOL supports selection, deployment and operations design for TXOne Element.
Where should we start?
ANSOL recommends starting with a current state assessment of your IT/OT environment. Scope confirmation, risk identification and prioritization are done first, followed by an improvement roadmap. Contact ANSOL to begin.
