Audit Logs

Blockchain-based storage and Microsoft sentinel

When integrated with advanced security platforms like Microsoft Sentinel, blockchain fortifies data integrity and lowers operational costs.


In the world of regulatory compliance, organisations are continually seeking innovative solutions to streamline processes, enhance security, and reduce costs. One groundbreaking technology that has emerged as a game-changer is blockchain-based enhanced audit. When integrated with advanced security platforms like Microsoft Sentinel, this dynamic duo fortifies data integrity and significantly lowers operational expenses for compliance teams.

Understanding the challenge

Traditional data storage and compliance systems face challenges related to data manipulation, unauthorised access, and the ever-present risk of tampering. Compliance teams entrusted with safeguarding sensitive information must ensure the integrity and authenticity of data to meet regulatory requirements. The traditional approach often involves hefty investments in secure, long-term storage infrastructure, such as traditional archiving solutions and sophisticated monitoring tools.

Enter blockchain-based immutable storage

Blockchain, a type of distributed immutable ledger, has proven its worth beyond the financial realms. Its decentralised and tamper-resistant nature makes it an ideal candidate for addressing the challenges faced by compliance teams. By leveraging blockchain-based enhanced audits, organisations can store and record data in a secure and tamper-proof format, rendering it impervious to unauthorised alterations.

Tamper-proof storage refers to the inability to modify or delete data once it has been recorded on the blockchain. Each data block is cryptographically linked to the previous one, forming a chain of blocks that creates a transparent and unalterable record. This ensures data integrity and provides an auditable trail, satisfying the stringent demands of regulatory bodies.

Blockchain’s synergy with Microsoft Sentinel

Microsoft Sentinel, a cloud-native Security Information and Event Management (SIEM) system is designed to provide intelligent security analytics and threat intelligence across a business. When integrated with blockchain-based enhanced audit, Sentinel gains a powerful ally in data integrity validation, and the combination delivers a robust, cost-efficient, secure ledger for compliance teams.

Enhanced security and compliance assurance

Integrating blockchain-based enhanced audit with Microsoft Sentinel strengthens an organisation’s overall security posture. Data stored on the blockchain becomes resistant to tampering, providing a secure foundation for compliance. This synergy ensures that the data used for compliance reporting is authentic and untampered, instilling confidence in regulatory bodies.

Reduced infrastructure costs

Traditional compliance solutions often require substantial investments in secure storage infrastructure, making redundancy options problematic. The decentralised nature of blockchain eliminates the need for highly centralised and expensive archive facilities. And new blockchain-based tools like LogLocker enable an organisation to increase redundancy through decentralised ledger technology enabling highly scalable and responsive data management and preservation.. 

When closely integrated with Microsoft Sentinel, Log Analytics and Azure Data Explorer (ADX), blockchain-based tools like LogLocker enable enterprise logs to be filtered, captured, retained and protected in a secure, tamper-proof ledger for long-term defensible preservation.

 This means that organisations can benefit from the inherent security features and enhanced audit of blockchain whilst also achieving significant cost savings, because you can leverage existing cloud-based storage solutions while minimising the risk of data manipulation

Compliance teams are constantly pressured to safeguard against data manipulation, a serious concern with severe legal and financial implications. Blockchain's immutability acts as a powerful deterrent to unauthorised alterations. Microsoft Sentinel, with its real-time threat detection capabilities, complements this by providing alerts and insights into potential security threats, further minimising the risk of data manipulation.

Auditable transparency

Regulatory audits often demand transparency in data handling and storage practices. The blockchain's tamperproof ledger provides an auditable trail of every data transaction, enhancing transparency and simplifying the auditing process for compliance teams. With its comprehensive logging and reporting capabilities, Microsoft Sentinel seamlessly integrates with tools like LogLocker to offer a holistic view of security events.

Time and resource efficiency

Integrating Microsoft Sentinel with a blockchain-based tool reduces the time and resources spent investigating and mitigating security incidents. The tamperproof nature of blockchain ensures that once data is recorded, it can be trusted, given the extensive verification processes it goes through. Sentinel's automated threat detection and response capabilities further expedite incident response, allowing compliance teams to operate more efficiently.

A match made in compliance heaven

If there’s a heaven for compliance teams, it’s the ability to both reduce costs and increase their business's compliance and security capabilities. 

The marriage of blockchain-based immutable storage and Microsoft Sentinel provides a revolutionary step towards the nirvana of cost-effective and secure compliance solutions. By leveraging blockchain's decentralised and tamper-resistant properties, organisations can fortify data integrity while reducing infrastructure costs. 

ByzGen, the people behind LogLocker, are enhancing this synergy between these two technologies. They are guided by a vision for a better future for compliance, one that may well be defined by the efficiency, security, and cost-effectiveness achieved through the seamless integration of blockchain technology and Microsoft Sentinel.
