Protect the Plant.
Without Stopping It.
Pragya secures the systems that run your operations: PLCs, SCADA, DCS, HMIs and the networks between them. We assess them, segment them, give you visibility into them and monitor them, without taking production offline.
IT Security Tools Weren't Built for the Plant Floor
Industrial networks were designed for uptime, not security. Industry 4.0, remote vendor access and IT-OT convergence have connected them to the outside world. Here's what we find most often during assessments:
- Unsupported operating systems on operator and engineering stations, with no antivirus and old patches
- Flat OT networks where one infected laptop can reach every controller
- Uncontrolled vendor access over TeamViewer, AnyDesk or plain RDP
- Multi-homed machines that quietly bridge firewall zones
- Default passwords on unmanaged switches and field devices
- Legacy protocols like SMBv1 still in active use
- No asset inventory, so nobody knows what is connected
Seven questions every plant leader should be able to answer
- How well do you understand what's in your industrial control system?
- How flat is your OT network, and is it truly separated from IT?
- Who needs remote access to your OT network, and how do you secure it?
- Do you know who can access what? When did you last check?
- Are there unsupported servers still running in your OT environment?
- Could you monitor OT and IT security from a single place?
- Have you considered sandboxing, deception or AI to strengthen OT defences?
If you can't answer them with confidence, start with an audit.
End-to-End OT Security, from Audit to Always-On
OT Security Audit Flagship
A 10-day, non-disruptive assessment of your plant's architecture, operations, assets and cyber risk, benchmarked against IEC 62443 and NIST.
Book Consultation →IT-OT Risk Assessment & Threat Modelling
Executive workshops that model real attack scenarios, such as phishing and ransomware, against your own architecture using MITRE ATT&CK for ICS.
Book Consultation →OT Asset Visibility & Anomaly Detection
Passive discovery of every PLC, RTU, HMI and workstation, including serial networks, plus detection of rogue communications, risky commands and known CVEs.
Book Consultation →Vulnerability Assessment & Penetration Testing
Gap, passive and active vulnerability assessments plus penetration testing scoped safely for live industrial environments.
Book Consultation →Secure Remote Access
Zero-trust access for vendors and remote engineers. Control by role, policy, activity and time window. Monitor, record and disconnect any session.
Book Consultation →Network Segmentation & Zoning
Zones and conduits per IEC 62443, an industrial DMZ at the IT-OT boundary (Purdue Level 3.5) and redesign of flat OT subnets.
Book Consultation →Endpoint & Plant-Floor Security
Virtual patching for legacy systems, application whitelisting, USB and removable-media control, and EDR for operator and engineering stations.
Book Consultation →OT Security Controls Implementation
Hands-on deployment of firewalls, segmentation, endpoint security, application control, deception and threat protection.
Book Consultation →Governance, Risk & Compliance
OT security policies, incident response SOPs, crisis management procedures and audit readiness for internal, regulatory and group-level reviews.
Book Consultation →Security Roadmap & Industry 4.0 Readiness
A prioritised roadmap that separates must-have from nice-to-have controls, with a solution blueprint and bill of materials ready for execution.
Book Consultation →OT Monitoring & Managed Services
Converged IT-OT SOC, OT SIEM integration, 24x7 NOC design and OT-specific anomaly monitoring.
Book Consultation →OT Security Training
A structured curriculum, risk assessment workshops and table-top exercises for plant, engineering and leadership teams.
Book Consultation →Engage. Assess. Implement.

Read case study →Common Questions
Will an OT security audit disrupt production?
No. We use passive, mirror-port traffic capture and never actively probe controllers. Our audits run on live plants.
How long does an audit take?
Typically 10 working days per site. Multi-site programmes can run sites in parallel.
Which standards do you assess against?
Mainly IEC 62443, NIST CSF, MITRE ATT&CK for ICS and NCIIPC guidelines, plus 22+ international and sector frameworks as required.
Do you only recommend, or do you also implement?
Both. Every audit ends with a bill of materials and scope of work, and our team can implement, monitor and train on the recommended controls.
Are you tied to a specific OT security vendor?
No. We partner with leading OEMs such as Claroty, Nozomi, TXOne, Fortinet and Check Point, and we recommend whatever fits your environment and risk.
Know Your OT Risk Before Attackers Do.
