• Last year, ČEZ detected 6.5 times more suspicious activity in its networks than three years ago.

• The newly launched security monitoring centre – the iSOC (Integrated Security Operations Center) oversees the protection of ČEZ Group in terms of physical, information, and cyber security.

• The protection of critical information infrastructure in the Czech Republic is one of the priorities of the newly established National Coordination Centre for Research and Development in the Field of Cyber Security.

The energy company ČEZ opened its new Integrated Security Operations Center – iSOC, which oversees the cyber security of ČEZ Group’s information systems, in the presence of senior representatives of the National Cyber and Information Security Agency (NÚKIB), Military Intelligence (VZ), and Czech Police (PČR). The centre’s task is not only to detect security events and incidents and activate the necessary countermeasures as quickly as possible, but also to oversee their effective resolution and, above all, to prevent security events in the future.

In terms of technical complexity, it will be one of the most demanding projects in the history of the Czech Republic, worth billions of crowns. The important project must not disrupt the operation of the key Czech emission-free power plant. Selected control and management systems will be partially renewed and upgraded by Westinghouse as their original supplier. Westinghouse has the greatest knowledge of its system, apart from CEZ itself, which strengthens the safe course of the upgrade.

ČEZ, a. s. with its seat at Prague 4, Duhová 2/1444, the Czech Republic (“CEZ”), is currently considering the disposal of its Bulgarian subsidiary CEZ ESCO Bulgaria EOOD, Id. No. 204 51 65 71, with its registered office at Sofia, Mladost District, 159 Tsarigradsko Shosse Blvd., BenchMark Business Centre, Post Code 1784, Bulgaria (the “Subsidiary”), indirectly owned by CEZ through its subsidiary CEZ Bulgarian Investments B.V., having its registered office at Herikerbergweg 157, 1101 CN Amsterdam, the Netherlands, and will be seeking submission of binding offers for acquisition of 100 % ownership interest in the Subsidiary (the “Transaction”).

The extraordinary June fundraiser among ČEZ Group employees in support of the Moravian municipalities affected by the tornado yielded more than CZK 2.7 million. The ČEZ Foundation matched that amount, sending over CZK 5.5 million crowns for specific projects. The money will help primarily with expenditures not covered by insurance. Immediately after the event, the ČEZ Foundation released CZK 10 million in emergency aid. In total, ČEZ helped the people of the Břeclav and Hodonín regions with CZK 15.5 million.
