Protect Critical Infrastructure Systems Against Cyberattacks

Close common identity system security gaps

Cyberattacks on critical infrastructure—specifically the energy sector—have long been a grave concern for cybersecurity experts, regulators, and government agencies. With incidents like the May 2021 ransomware attack on Colonial Pipeline—which crippled oil and gas distribution, raised prices, and incited panic—the danger has hit home for all of us.  

 IT and security teams at infrastructure organizations involved with utilities, energy, transportation, water/wastewater, and other essential services face multiple challenges: 

  • Legacy technologies 
  • Outdated security practices 
  • Limited budgets 
  • Siloed IT and security teams 
  • Multiple players across private and public sectors 
  • Deployment of digital and networked equipment, providing new targets for cybercriminals—and far-reaching consequences 

Cyberattacks against critical infrastructure are on the rise.

Active Directory is a common target for bad actors targeting critical infrastructure

The most notorious recent cyberattacks—with global consequences—have targeted critical infrastructure systems. The attacks on SolarWinds, Colonial Pipeline, and the Irish Health Service are just a few—and the list grows weekly. Because many utilities manage infrastructure critical to daily life, nation states and other malicious actors have an interest in developing cyber weapons that target utilities, according to a Siemens/Ponemon Institute survey of global utility companies. While the cyberattack is underway, essential services come to a standstill. 

Gain Control of Critical Infrastructure Security

Semperis gives critical infrastructure organizations first-of-its-kind solutions to address the entire lifecycle of an identity attack—finding and fixing security vulnerabilities, intercepting cyberattacks in progress, and quickly responding to ransomware, wiper attacks, and other cyber disasters.


Critical infrastructure attacks often start with cybercriminals exploiting Active Directory weaknesses to gain access to critical information systems.


Semperis uncovers security gaps in Active Directoryincluding Incidents of Exposure, such as configurations that have drifted over time, and Incidents of Compromise, such as evidence of malicious activity.


After breaching the victim organization’s information systems, attackers can move throughout the network, often undetected by traditional SIEM solutions, before unleashing malware.


Semperis identifies attacks that bypass agent-based or log-based detection and provides autonomous rollback of suspicious activity.


Cyberattacks can bring critical infrastructure—including oil and gas distribution, water supply systems, and public health systems—to standstill, preventing access to essential public services and threatening public safety.


Semperis cuts the time to fully recover Active Directory from days or week to minutes—speeding resumption of normal operations and closing security gaps so cybercriminals can’t attack again.  

How to Defend Against Ransomware-as-a-Service Groups That Attack Active Directory

“The stakes are much higher in an attack like Colonial Pipeline—both for the threat actors and their victims. I think this is an implication of what’s to come in the future—open season on infrastructure providers.”
