# Best Blockchain Security Software *By [Brandon Summers-Miller](https://research.g2.com/insights/author/brandon-summers-miller)* Blockchain security solutions are designed to protect information stored on a specific blockchain and can be applied to a wide range of data storage systems. These tools operate by analyzing a blockchain ecosystem, evaluating risks, and detecting threats to information, applications, and digital assets. These security solutions are typically used to detect fraudulent transactions and identify threats to a blockchain, as well as protecting smart contracts and tokenized assets. Companies also use these tools to ensure data is protected from various risks and stored in compliance with data protection and/or privacy guidelines. Blockchain security tools differ from blockchain analysis solutions in that they facilitate the actual protection of data; blockchain analysis software supports more in-depth investigation to individual ledgers, identities, and transactions. Blockchain security software may have similar features to other security solutions that may not be designed specifically for securing a blockchain. To qualify for inclusion in the Blockchain Security category, a product must: - Be built upon on a blockchain-based platform or distributed ledger technology (DLT) system - Enforce identity and authentication verification prior to writing to a permissioned blockchain (versus a public, permissionless blockchain), to ensure the integrity of the blockchain - Monitor and detect threats to a blockchain ecosystem - Protect smart contracts and tokenized assets ## How Many Blockchain Security Software Products Does G2 Track? **Total Products under this Category:** 38 ## How Does G2 Rank Blockchain Security Software Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 100+ Authentic Reviews - 38+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts. Each product is measured using the same transparent criteria, with no paid placement or vendor influence. While reviews reflect real user experiences, which can be subjective, they offer valuable insight into how software performs in the hands of professionals. Together, these inputs power the G2 Score, a standardized way to compare tools within every category. ## Which Blockchain Security Software Is Best for Your Use Case? - **Best Free Software:** [Dfns](https://www.g2.com/products/dfns/reviews) ## What Are the Top-Rated Blockchain Security Software Products in 2026? ### 1.
