Cybersecurity Resources

From security updates and product support to cybersecurity training and free awareness aids, SEL provides resources that help your organization maintain a strong cybersecurity posture.

SEL products and solutions have been designed with cybersecurity in mind from the beginning. When we brought the world’s first digital protective relay to market in 1984, we included security features that set the baseline for all protective relays.

Today, we continue our industry leadership by developing new cybersecurity products for critical infrastructure; contributing to standards development through IEEE, NERC, NIST, IEC, and various industry associations; and offering training that helps the owners and operators of critical infrastructure keep up with cybersecurity best practices.

SEL Security Updates and Support

All SEL products are designed for a service life of at least 20 years, and we provide cybersecurity bulletins and updates for the full lifetime of every device we manufacture.

Our certified security professionals are available to help you develop the proactive and sustainable plans, policies, and procedures you need to stay ahead of cyber threats. Our solutions can be applied to your unique security needs and make it easier to meet and address today’s regulatory standards.

Free Cybersecurity Resources

Industry associations and U.S. government agencies provide a broad array of free resources and best-practices information to help asset owners and operators secure their critical infrastructure.

These resources do not directly address regulatory requirements. Instead, they provide a broad set of best practices and information intended to help asset owners and operators secure their critical infrastructure.

American Water Works Association (AWWA)

AWWA provides actionable information utility owners and operators can take to secure their process control systems.


Use the assessment tools and informational resources provided by the IEC to help ensure the security and interoperability of electrical protection and control systems.


The IEEE helps security professionals improve the design and implementation of cybersecure systems and provides practical guides to improving your system’s cybersecurity.


NRECA works with member companies to provide tools that help electrical cooperatives meet cybersecurity goals and standards.

U.S. Department of Energy (DOE)

The DOE provides many resources to help American industries and electricity providers keep their protection and control systems secure.

U.S. Department of Homeland Security (DHS)

The DHS provides cybersecurity assessment tools and response roadmaps to help improve the security of all critical infrastructures that employ energy control systems.

U.S. National Institute of Standards and Technology (NIST)

NIST works with industry partners to develop cybersecurity standards and best practices and provides tools that help electrical system owners implement them.

Power System Risk Mitigation

We have outlined some practical steps you can take right now to mitigate risk to your power system from cyber attacks, geomagnetically induced current, and geomagnetic disturbances.

Cybersecurity Awareness and Education

Because cybersecurity is provided not only by devices and software, but also by people, we provide awareness and education materials—many of which we use in our own engineering, corporate, and manufacturing facilities—to help keep everyone up to date on security risks and best practices.
