Utilities play an essential role in any country and are therefore classified by governments as critical
infrastructure. The failure of the the energy supply initiates a chain reaction that quickly affects all connected customers
and causes major outages and disruptions in everyday life. However, critical infrastructure and particularly important web
applications can be effectively secured by Link11 protection solutions.

Cautionary examples in the past

Probability of cyber attacks
is rapidly increasing for utilities

Many of us take our energy supply for granted. After all, without electricity, the most basic things no longer work – lights no longer turn on, the refrigerator defrosts, the Internet goes bye-bye, and even the computer can only be operated on battery power at best. A power outage causes widespread problems and becomes more serious the longer it lasts. An ongoing DDoS attack with high bandwidths has the potential to create such scenarios. Unfortunately, the past has proven that crippling cyber-attack outages are not far-fetched. Therefore, securing our energy infrastructure from malicious online threats should be a top priority.

With Link11’s DDoS Protection, not only the energy infrastructure, but all the web applications running on it can be fortified against harmful attacks.

Cyber security as a central anchor for the utilities future


For essential utilities, downtime is not an option

The utilities industry is “critical infrastructure”, and cyberattack trends show that attackers focus on companies with highly critical systems

Rollout of smart meters that enable digital measurement of consumption are potential weak points


Smart cities, power plants, control centers, and power grids can be brought to a standstill by cyber attacks. The result is “supply shortages”

Financial but also increasingly political motives for attacks

The security of smart meters is an issue, but the protection of relevant APIs is an even bigger issue

  • Secured against OWASP Top 10 threats

Increased security measures apply to critical infrastructures

In Germany, the state mandates increased security for critical infrastructures.
This regulation is anchored in the IT Security Act and provides for various types of
  • A minimum level of IT security must be maintained at all costs
  • The security measures used must be state of the art
  • Protection of customer data must demonstrably have top priority
  • Protection standards must be regularly monitored
  • For operators of critical infrastructure (= KRITIS), there is a special obligation to report as soon as a security breach occurs.
