What ARIS delivers
We do not stop at producing a report. We organize findings in a way that management, auditors, and technical teams can all use, and translate them into actionable next steps.
Key security challenges
Security risk now spans internet-facing systems, cloud configurations, identity management, IT/OT boundaries, industrial endpoints, and plant operations.
Web / API exposure
Authentication flaws, authorization gaps, and unpatched weaknesses in public-facing systems can become direct entry points for attackers.
Weak IT / OT segmentation
When IT and OT are not clearly separated, a breach can spread laterally and increase the risk of operational disruption.
Configuration and access issues
Cloud misconfigurations, excessive privileges, stale credentials, and exposed storage remain common and often overlooked.
Gaps in operations and governance
Without incident plans, monitoring, training, and clear responsibilities, response time and decision quality both suffer.
Why security initiatives stall
Many programs struggle not because of tools alone, but because prioritization, operational fit, and continuous improvement are missing.
Assessment without follow-through
Issues are found, but validation and re-testing are often not built into the engagement.
OT constraints are ignored
Production environments cannot always be treated like standard IT environments.
Priorities are unclear
Severity alone is not enough. Business and operational impact must also be considered.
No continuous improvement loop
Without monitoring, governance, training, and review, the same weaknesses often return.
How the engagement works
We define the scope, assess safely, and convert the results into practical remediation actions.
Scoping and rules of engagement
We define target systems, goals, constraints, OT safety rules, communication routes, and testing boundaries.
Discovery and assessment
We review assets, architecture, exposure, configuration, access control, and security boundaries to understand real risk.
Remediation planning and validation
We prioritize actions, explain the findings clearly, and can support validation and re-assessment after fixes.
Service scope
ARIS supports both point-in-time assessments and longer-term security improvement programs across IT and OT.
Assessment Test
- Review the current security posture and identify major gaps
- Useful before roadmap planning, audits, or governance improvement
Vulnerability Test
- Assess Web, API, Network, Server, and Cloud security weaknesses
- Provide practical input for remediation prioritization
Penetration Test
- Validate exploitability and likely business impact
- Well suited for higher-risk or higher-exposure systems
SOC / SIEM
- Support log aggregation, monitoring, alerting, and investigation capability
- Improve continuous visibility and faster detection
Security Consulting
- Security Guideline, CSIRT, Incident Response, Supply Chain Security
- Support alignment with ISO 27001, NIST, IEC 62443, and similar frameworks
Security Solution Integration
- Support Firewall, IDS/IPS, WAF, Endpoint Security, SIEM, and related solutions
- From solution selection to implementation and operational fit
OT / ICS Security
- Assess IT/OT boundaries, segmentation, industrial endpoints, and operational risk
- Use an availability- and safety-first approach for OT environments
Standards and coverage
We structure the work so the outputs are useful for technical teams, operations, audits, and compliance discussions.

Why ARIS Vietnam
We connect IT security and OT security, and we stay focused on execution after the assessment.
IT and OT together
We look across enterprise IT and OT/ICS as one risk landscape.
Safety-conscious OT methods
We prioritize approaches that respect uptime, safety, and operational constraints.
Standards-aware delivery
We can align findings with IEC 62443, NIST, ISO 27001, and related frameworks.
Support through remediation
We can continue through remediation review, validation, and re-assessment.
Frequently asked questions
Common questions from organizations planning a security or OT security initiative.
OT security protects operational environments such as factories, PLCs, SCADA, and industrial endpoints. Compared with IT security, it puts stronger emphasis on availability and safety in environments that are difficult to stop or patch.
It is suitable for companies running web applications, APIs, cloud, networks, and servers, as well as manufacturers, logistics operators, utilities, and organizations with OT/ICS environments.
Yes. We prioritize passive visibility and safety-conscious methods so that assets and risks can be assessed while minimizing production impact.
We handle live OT very carefully. Unless strict safety conditions are met, testing is generally planned in isolated or production-like environments.
We can align the work with IEC 62443, NIST, ISO 27001, OWASP, and other audit or compliance requirements relevant to the client.
Yes. We can support prioritization, configuration reviews, remediation planning, validation, and re-assessment.
TXOne Element is relevant when an organization wants stronger protection for OT endpoints and field computers, including USB control and application control.
A scoping session is usually the best start. It helps define priority systems, risk areas, operational constraints, and the right assessment approach.
