The OT challenge

Why OT Is a Different Security Problem

From credential sprawl to ungoverned vendor access, here's what's actually broken in most OT environments.

Remote access
tool sprawl

Most OT environments run four or more remote access tools simultaneously — each with its own credentials, its own audit trail, and no central governance over any of them.

Hardcoded and
shared credentials

Shared SCADA passwords, factory-default PLC credentials, and hardcoded service accounts that have never been rotated exist in nearly every OT environment today.

Ungoverned
VPN access

VPNs give vendors and contractors broad access to the entire OT network rather than specific devices, with no session visibility and no automatic revocation when the work is done.

No lateral
movement controls

Without least privilege enforcement at the session level, a single compromised entry point gives an attacker unrestricted movement across your entire OT network.

No automated
access provisioning

Most OT access requests are managed over email and spreadsheets, with no automated workflows, no role-based controls, and no audit trail of who approved what or when.

Compliance gaps
that bind operations

NERC CIP, IEC 62443, and NIST 800-82 require granular access controls and audit-ready reporting that most legacy OT tools simply weren't built to provide.

Two teams,
one attack surface

IT and OT teams run different tools, different priorities, different reporting lines. Privileged access falls through the gap, ungoverned on both sides.

Assets spread
across remote sites

Substations, refineries, water plants, pipelines. Governing access across distributed OT assets is a different challenge than securing a single facility.

Physical
consequences

A breach in IT means compromised data. In OT it means a pipeline stops, a substation goes dark, or a water treatment plant fails. The consequences are physical, not just financial.

What Securden does

Complete privileged access control.
Across every OT system.

Whether you run an energy grid, a water plant, or an oil refinery, Securden
gives you full control over who accesses your critical systems, when, and for how long.

Agentless access

Reach every OT system without installing anything on it

Securden connects to legacy ICS, SCADA, and PLCs over the protocols they already speak — RDP, SSH, VNC, SQL, and Telnet. No agents, no reboots, no certification risk. OEMs, contractors, and integrators launch through the same governed gateway instead of a flat VPN.

  • Works with legacy ICS, SCADA, and PLCs as-is
  • RDP, SSH, VNC, SQL, and Telnet out of the box
  • Replaces vendor VPN with a scoped, session-level gateway

Just-in-time access

Grant access only when it's actually needed

No permanent privileges, no standing access. Every request runs through a multi-level approval workflow, opens a time-bound window, and closes itself when the window expires — with the password rotated on the way out.

  • Eliminate standing privileges across OT systems
  • Multi-level approvals for internal users and vendors
  • Automatic revocation and password change after use

Session recording

A full audit trail of every privileged session

Every action taken on your OT systems is recorded and replayable. Search keystrokes, export SSH command logs with timestamps, and share a recording with a third party for a limited window during an investigation.

  • Record every privileged session across ICS and SCADA
  • Search, replay, and export session logs on demand
  • Anomaly detection flags unusual session behavior in real time
Recorded Sessions table listing session address, login name, start and end time, with playback and export controls.
Credential vault

One vault for every identity across IT and OT — human or not

Bring every password, key, certificate, and machine credential under central control. From operator accounts to the service accounts and automation scripts running your ICS, nothing stays hardcoded in a config file.

  • Discover and onboard credentials across distributed OT assets
  • Eliminate hardcoded credentials in ICS and automated workflows
  • Launch remote connections without ever revealing the password

Policy & rotation

Strong policy, enforced automatically — not by reminder emails

Set password policy once and let Securden hold the line: expired-password rotation, remote verification and reset, breached-password identification, and expiry notifications across every account you govern.

  • Scheduled rotation, after every use, or on vendor checkout
  • Remote password verification and reset across OT assets
  • Breached-password identification and expiry notifications
Password policy settings grouped into account management, JIT workflow, self-service, notifications, and high availability.
Audit & compliance

Always ready for your next audit

Securden captures every account activity as a tamper-proof audit trail and maps it to NERC CIP, IEC 62443, and NIST 800-82. Generate the report your auditor asked for, on demand, or schedule it to arrive before they do.

  • Pre-built reports for NERC CIP, IEC 62443, and NIST 800-82
  • Tamper-proof audit trails across every OT session
  • Scheduled exports and continuous compliance monitoring

Frequently asked questions

plus icon minus icon
What is PAM for OT, and how is it different from traditional PAM?

Privileged access management for OT governs who can access industrial control systems, SCADA, PLCs, and other critical infrastructure assets. Unlike traditional PAM, which is designed for IT environments, PAM for OT must work with legacy systems that can't be patched or rebooted, operate without installing agents on target systems, and account for the physical consequences of a security incident. Securden extends privileged access controls across both IT and OT from a single platform, without requiring changes to your existing environment.

plus icon minus icon
Does Securden require software installation on OT systems like PLCs or SCADA?

No. Securden is agentless — it connects to OT systems through standard protocols like RDP, SSH, VNC, and Telnet without installing any software on the target system. This means no reboots, no certification risk, and no disruption to your operations. Your OT environment stays exactly as it is.

plus icon minus icon
Can Securden be deployed in air-gapped OT environments?

Yes. Securden supports full on-premise deployment with complete feature parity. For organizations with air-gapped environments or strict data residency requirements, on-premise deployment gives you complete control over your infrastructure without relying on cloud connectivity.

plus icon minus icon
How does Securden help with NERC CIP compliance?

Securden maps privileged access controls directly to NERC CIP requirements. It maintains tamper-proof audit trails of every privileged session, enforces least privilege and just-in-time access policies, manages and rotates service account credentials automatically, and generates audit-ready reports on demand. Organizations using Securden can demonstrate compliance with NERC CIP's access control, monitoring, and change management requirements without manual effort.

plus icon minus icon
How does Securden handle third-party and vendor access in OT environments?

Securden eliminates standing privileges for third-party vendors entirely. OEMs, contractors, and integrators get time-bound, monitored access through a secure gateway — no VPN required, no permanent credentials, no ungoverned sessions. Every vendor session is recorded end to end and automatically revoked when the access window closes. Your OT team retains full visibility and control over every external connection.

plus icon minus icon
Does Securden work with legacy ICS and SCADA systems?

Yes. Securden is designed to work with your existing infrastructure, including legacy ICS and SCADA systems that other PAM tools can't reach. It connects through standard protocols your systems already support, without requiring upgrades, replacements, or changes to your existing environment. Your workflows stay intact while meeting modern security and compliance requirements.

plus icon minus icon
How long does it take to deploy Securden in an OT environment?

Most organizations are fully deployed within weeks. Implementation is straightforward enough for your existing IT team to manage, with professional services available if needed.
