This interview is part of our new Blockchain In Cybersecurity series, where we interview the world's leading thought leaders on the front lines of the intersections between blockchain and cybersecurity.

In this interview we speak with Bozhidar Bozhanov, CEO of LogSentinel, to understand how his company is using blockchain to transform the cybersecurity business, and what the future of the industry holds.

1. What’s the story behind LogSentinel? Why and how did you begin?

BB: Digital events in IT systems must leave a trail. The two cofounders realized that when we worked on e-government projects in the Bulgarian government. But there was no secure solution to hold the audit trail, and that’s true for millions of systems around the world – in the public and private sectors. So roughly a year after we left the government, we started the company in order to solve that problem.

2. Please describe your use case and how LogSentinel uses blockchain:

BB: We figured that the cryptography underlying blockchain is a great fit for protecting the integrity of data. While current solutions simply keep the audit trail in a typical database or even text files, we decided to use the cryptographic guarantees of blockchain to make sure that nobody tampered with the audit logs – not even system administrators.

3. Could you share a specific customer/user that benefits from what you offer? What has your service done for them?

BB: We had a successful Proof of Concept with a big bank – in the pilot we protect all digital events that happen in their core banking system.

In another interesting use case, we donated our solution to the Bulgarian government and it’s used to protect all accesses to personal data in government registers, which means nobody could read your data and then cover their tracks.

In another project, we are also protecting the data of online tenders, guaranteeing that no party can claim its bid was not correctly stored or was later removed by the administrators.

4. What other blockchain use cases in cybersecurity are you excited about?

BB: Protecting data integrity is, we believe, the best use case for blockchain in cybersecurity and that’s why we picked that technology to solve this problem. Other use cases are not that obvious, but introducing blockchain in some form would generally increase security because it is already based on a good set of cryptographic principles and the ability to prove to third parties that some information is correct.

5. Where will LogSentinel be in 5 years?

BB: Serving thousands of customers to protect the integrity of their data, using our cutting edge technology.
