External Attack Surface Management for OT, ICS & Critical Infrastructure
ShiftSix continuously maps internet-exposed assets, remote access pathways, and OT/ICS entry points — then prioritizes exposures using real adversary behavior and OT-aware context. No agents. No scan windows. No stale reports.

Industrial Exposure Intelligence
Continuous Threat Exposure Management (CTEM) is a five-stage program — scoping, discovery, prioritization, validation, and mobilization designed to continuously reduce an organization’s exploitable attack surface.
For industrial environments, exposure isn’t theoretical. Ransomware groups like Qilin, Akira, and Play are actively targeting manufacturing, energy, and transportation while nation-state actors pre-position inside critical infrastructure for future disruption. ShiftSix correlates your external exposure against active adversary campaigns matching internet-facing OT assets, remote access pathways, and misconfigured services to the threat groups targeting your sector right now.
Gartner projects that by 2026, organizations prioritizing continuous threat exposure management will be three times less likely to suffer a breach than those relying on point-in-time assessments. — Gartner, Implement a Continuous Threat Exposure Management (CTEM) Program, July 2022
How ShiftSix Operationalizes CTEM
Enumerate
Build the inventory attackers already have.
Continuously identify every externally visible asset — IT infrastructure, OT/ICS entry points, remote access interfaces, cloud services, and shadow systems — from an attacker’s perspective. If it’s reachable from the internet, it’s part of your attack surface.
Correlate
Prioritize based on real-world threats
Map each exposure against exploit-in-the-wild data, ransomware tradecraft, and sector-specific threat actor TTPs. Replace theoretical CVSS scores with adversary context — so you focus remediation on what attackers are most likely to weaponize first.
Close
Reduce measurable exposure risk.
Deliver threat-contextualized remediation guidance to the teams who own the risk. Track whether the exposure is actually removed from the live external surface — and measure risk reduction continuously, not quarterly.

ShiftSix vs. OT Network Monitoring Platforms
Network monitoring tools like Claroty and Dragos provide visibility inside your OT network. ShiftSix provides the outside-in view attackers already have — before they ever reach it.
| ShiftSix | Claroty | Dragos | |
|---|---|---|---|
| Approach | Outside-in (EASM) | Inside-out monitoring | Inside-out monitoring |
| Sensors or agents required | ✓ None | Multiple (sensors, agentless, active queries) | Passive sensors (active collection optional) |
| Touches your OT network | ✓ Never | Passive tap + active queries | Passive tap |
| Attacker-perspective visibility | ✓ Yes | No | No |
| CISA KEV correlation | ✓ Native | Native | Limited |
| Deployment | SaaS — no hardware | SaaS + On-prem | SaaS + On-prem |
| Primary use case | Pre-breach exposure visibility | Network monitoring + exposure management | Network monitoring + vulnerability management |
Why Security Teams Choose ShiftSix
Security teams choose ShiftSix because visibility gaps are where attackers operate. Our platform continuously maps the attack surface your existing tools don’t see — internet-exposed assets, shadow IT, misconfigured remote access, and OT/ICS entry points. We give you an attacker’s perspective so you can act on real risk, not theoretical exposure.
No agents. No network access required. Just continuous, actionable attack surface intelligence — delivered automatically so your team spends less time searching and more time reducing risk.
Common Questions
What is Continuous Threat Exposure Management (CTEM)?
Continuous Threat Exposure Management (CTEM) is a cybersecurity framework defined by Gartner in 2022 that continuously scopes, discovers, prioritizes, validates, and mobilizes remediation of security exposures. Unlike point-in-time assessments, CTEM runs as an ongoing cycle — making it critical for OT and ICS environments where new exposures emerge daily. ShiftSix operationalizes CTEM into three steps: Enumerate, Correlate, and Close.
What is External Attack Surface Management (EASM)?
External Attack Surface Management (EASM) is the process of continuously discovering, inventorying, and monitoring all internet-facing assets an organization owns — including those in OT, ICS, and industrial edge environments — to identify and remediate exposures before attackers can exploit them. Unlike internal vulnerability management, EASM operates from the outside in, the same way an attacker would map your environment.
How is ShiftSix different from Claroty or Dragos?
Claroty and Dragos are OT network monitoring platforms that provide inside-out visibility into traffic and behavior within your industrial network. ShiftSix is an OT-native EASM and CTEM platform that provides outside-in exposure intelligence — mapping what attackers can reach from the internet before they ever reach your OT network. ShiftSix requires no agents, no scan windows, and never touches your OT network. It is designed to complement existing OT monitoring tools, not replace them.
How does ShiftSix map to regulatory and industry frameworks?
ShiftSix maps discovered external exposures against NERC CIP, IEC 62443, NIST CSF 2.0, NIS2, MITRE ATT&CK for ICS, and CISA ICS-CERT advisory frameworks — giving operators continuous compliance posture evidence alongside their exposure data. This reduces manual evidence-gathering overhead and accelerates audit readiness across multiple regulatory frameworks simultaneously.
