Abstract. Introduction. With the development of data transmission and processing systems and the transfer of an increasing number of business processes of enterprises and organizations to the online mode, the problem of data protection arises. The greatest risks are associated with financial organizations that operate with a signifi-cant amount of financial resources. The convenience and economy of digital banking services carry certain risks: now, in order to rob a bank, it is enough to find a loophole in the banking software. In turn, banks now protect not only their physical branches, but also virtual ones. Purpose: to study the current trends in the impact of information security threats on the largest subjects of the Russian economy, taking into account the development of domestic and global technological solutions. Materials and methods. The paper uses materials from periodicals, data on the financial and economic activities of individual enterprises of the domestic economy. Research results, discussion. The growing demand for security systems is associated with a noticeable increase in cybercrime. The number of hacker attacks in the world continues to grow rapidly, especially against the back-ground of the hasty transition of many companies to remote work. Russian companies working in the field of information security complain about the lack of investment to create new products. The capacity of the domestic Russian IT market does not allow domestic companies to scale their business and attract investor funds for development. Cyber threats are evolving at a rapid pace, now cybercriminals are technically very advanced groups, their business is estimated at billions of dollars. To counter such a powerful shadow business, information security companies themselves need significant investments. Theft, leakage, and destruction of data can have serious consequences for citizens, businesses, and the state as a whole. One of the solutions for the protection of information is the development of quantum communications, which provide the highest degree of data transmission protection available today. Conclusion. Despite the objective difficulties, work in the direction of information security in the banking and telecommunications sectors is quite active, but in our opinion, more active participation of the state is necessary, including taking into account the significant, but unused resources of the National welfare fund in the economy.
