# 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:** 41 ### Category Stats (Jul 2026) - **Average Rating**: 4.41/5 (↑0.04 vs Jun 2026) The average rating of products in this category, based on all submitted ratings *Last updated: July 09, 2026* ## How Does G2 Rank Blockchain Security Software Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 100+ Authentic Reviews - 41+ 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.

[Dfns](https://www.g2.com/products/dfns/reviews) DFNS is a core banking platform for digital assets. It gives banks, fintechs, and enterprises the infrastructure to run financial operations and build products onchain, provisioning wallets, securing keys, governing transactions, and servicing tokenized assets across blockchains, the way a traditional core banking system underpins accounts, payments, and ledgers in conventional finance. The platform addresses a structural gap. The core systems financial institutions run today were not built for assets that settle in seconds, on public networks, with cryptographic ownership. Rather than replacing an organization's existing core banking system, hardware security modules, or compliance stack, DFNS provides the layer that lets those systems operate onchain. It is delivered as composable modules through one REST API and SDKs, so an organization can adopt a single capability or the full platform, and it connects to more than 100 blockchains and third party services through a single integration surface. Over 400 institutional and fintech clients run on DFNS, including Standard Chartered, First Abu Dhabi Bank, IBM, Stripe, Circle, Kraken, and Apex Group. Roughly 1% of all global stablecoin payment volume settles through the platform. DFNS is used across digital asset custody, banking, embedded wallets, stablecoin payments, trading operations, tokenization, and treasury and asset management. The platform is organized into modules, including: 1. Wallet-as-a-Service — create, index, and manage wallets across 100+ blockchains and third party services, as one account layer for custody, payments, trading, treasury, and tokenization. 2. Transaction Management — format, approve, decode, simulate, sign, broadcast, and track transactions at scale, built for high volume flows and complex approval logic. 3. Treasury Management and Tokenization Engine — manage onchain treasury across entities, currencies, and networks, and issue and service tokenized assets across their full lifecycle. 4. Policy Engine and Governance Engine — enforce limits, allowlists, quorums, roles, and ABI aware approvals before every signature, and cryptographically verify every intent, policy, and signature against a state the customer controls, deployed within their own perimeter. 5. Key Management — run keys across MPC, HSM, TEE, or BYOK models, with production grade protocols built for resilience, scale, and no single point of failure. A defining characteristic is that authentication and transaction signing are handled as separate functions, and policies are evaluated before any signature is produced, giving organizations programmable control over who can move which assets, under what conditions. Keys are operated so that a complete private key is never assembled in one place. DFNS can be deployed as managed SaaS, hybrid, or fully on premises. The deployment model changes while the modules and controls stay the same, allowing key material and infrastructure to be placed according to regulatory and operational requirements. It integrates with existing systems including core banking platforms, custody and compliance tooling, and payment rails, and organizations typically adopt it to add digital asset capabilities to existing products, to meet requirements under frameworks such as MiCAR and DORA, or to consolidate wallet, transaction, governance, and settlement operations onto one platform. **Average Rating:** 4.8/5.0 **Total Reviews:** 34 **Who Is the Company Behind Dfns?** - **Seller:** [Dfns](https://www.g2.com/sellers/dfns) - **Company Website:** https://www.dfns.co/ - **Year Founded:** 2020 - **HQ Location:** Paris, FR - **Twitter:** @dfnsHQ (4,156 Twitter followers) - **LinkedIn® Page:** https://linkedin.com/company/dfnshq (87 employees on LinkedIn®) **Who Uses This Product?** - **Who Uses This:** CEO - **Top Industries:** Financial Services - **Company Size:** 79% Small-Business, 15% Mid-Market #### What Are Dfns's Pros and Cons? **Pros:** - Customer Support (11 reviews) - Ease of Use (8 reviews) - Comprehensive Features (4 reviews) - Easy Integrations (4 reviews) - Security (4 reviews) **Cons:** - Missing Features (4 reviews) - Complexity (3 reviews) - UX Improvement (3 reviews) - Poor Usability (2 reviews) - Integration Issues (1 reviews) ### What Do G2 Reviewers Say About Dfns? *AI-generated summary from verified user reviews* **Pros:** - Users highlight the **responsive and knowledgeable customer support** , ensuring quick and efficient implementation of DFNS API. - Users commend the **ease of use** of Dfns, highlighting quick implementation and a user-friendly dashboard. - Users value Dfns for its **comprehensive features** , including robust wallet infrastructure and continuous improvements, enhancing usability and efficiency. - Users find Dfns’ **easy integrations** beneficial, streamlining project delivery and enhancing overall operational efficiency. - Users commend Dfns for its **robust security features** , including MPC wallets and scalable key management systems. **Cons:** - Users note the **lack of useful features** in Dfns, indicating a need for better API support and wider compatibility. - Users find the **complexity** of the Dfns API and wallet management challenging, impacting overall usability. - Users find the **UX improvement necessary** due to impractical dashboard design and missing essential features. - Users find the **poor usability** of Dfns challenging due to confusing MPC messages and complex wallet management. - Users find the **limited support for USDT** constraining, impacting operations in several markets and integration needs. #### What Are Recent G2 Reviews of Dfns? **"[Effortless Setup and Robust Wallet Infrastructure with Constant Updates](https://www.g2.com/survey_responses/dfns-review-11864645)"** **Rating:** 4.5/5.0 stars *— Ibahima S.* [Read full review](https://www.g2.com/survey_responses/dfns-review-11864645) --- **"[Highly Customizable, Surprisingly Efficient](https://www.g2.com/survey_responses/dfns-review-12793087)"** **Rating:** 4.5/5.0 stars *— Franz S.* [Read full review](https://www.g2.com/survey_responses/dfns-review-12793087) --- ### 2.

[Nominis Vue](https://www.g2.com/products/nominis-vue/reviews) NOMINIS: Crypto Compliance, KYT, and Forensic Intelligence in One Platform NOMINIS is an AI-powered crypto compliance and blockchain intelligence platform built for Virtual Asset Service Providers (VASPs), exchanges, crypto fintechs, and law enforcement agencies that need enterprise-grade transaction monitoring without enterprise-level complexity or cost. The platform consolidates wallet screening, Know Your Transaction (KYT), forensic investigation, and crypto intelligence into a single workspace, giving compliance teams everything required to detect illicit activity, prevent sanctions exposure, and meet AML/CTF obligations across 70+ blockchains. What sets NOMINIS apart is its multi-source intelligence approach. Most legacy tools rely primarily on source-of-funds analysis. NOMINIS combines on-chain transaction data with off-chain signals from dark web, deep web, OSINT, SOCMINT, and HUMINT sources, then layers behavioral analytics on top. The result is deeper contextual risk scoring and the ability to attribute wallets even when verified sources are limited. The company maintains one of the largest crypto terror-financing databases in the industry and has been credited with helping flag over $10 billion in illicit crypto activity. Core capabilities include: Wallet Screening: Pre-transaction risk assessment for inbound deposits, onboarding addresses, and counterparties, with exposure checks against mixers, sanctioned entities, and fraud clusters. Know Your Transaction (KYT): Continuous monitoring across 70+ blockchains with real-time alerts on suspicious flows, rapid chain hops, mixer interactions, and laundering typologies. Forensic Tools: Wallet graph exploration, money flow tracing, case files, and evidence exports for investigators and law enforcement. AsKYT, Intelligence as a Service, and Research: Custom investigations and crypto intelligence delivered by NOMINIS analysts. The platform is built for global regulatory readiness, with coverage aligned to FATF, MiCA, FinCEN, FINTRAC, VARA, ADGM, and AMLD5 frameworks. Compliance officers can adjust risk scoring rules without engineering involvement, manage cases end-to-end, and export defensible reports for regulators, auditors, or LEAs. API and UI access are included on every plan, and the system supports automated or manual responses (block, flag, escalate) with full audit trails. Pricing is transparent and volume-based, starting at $350/month for Starter (350 checks) and scaling through Growth and Growth+ tiers up to fully custom enterprise deployments. Annual billing offers meaningful discounts, there are no implementation fees, overage is billed at a published per-call rate, and a 7-day free trial is available with no credit card required. NOMINIS positions itself as a focused alternative to legacy KYT tools for VASPs that need accurate, defensible risk screening and investigations without the cost or complexity of forensic-grade tooling they don't actually need. **Average Rating:** 2.5/5.0 **Total Reviews:** 1 **Who Is the Company Behind Nominis Vue?** - **Seller:** [Nominis](https://www.g2.com/sellers/nominis) - **Year Founded:** 2023 - **HQ Location:** Tel Aviv, IL - **Twitter:** @nominisio (2,181 Twitter followers) - **LinkedIn® Page:** https://www.linkedin.com/company/nominisio (15 employees on LinkedIn®) **Who Uses This Product?** - **Company Size:** 100% Enterprise #### What Are Nominis Vue's Pros and Cons? **Pros:** - Ease of Use (1 reviews) - Easy Integrations (1 reviews) - Real-time Monitoring (1 reviews) **Cons:** - Poor Customer Support (1 reviews) ### What Do G2 Reviewers Say About Nominis Vue? *AI-generated summary from verified user reviews* **Pros:** - Users appreciate the **ease of use** of Nominis Vue, praising its clean interface for tracking risky transactions effortlessly. - Users highlight the **easy integrations** of Nominis Vue, which enhance transaction monitoring and streamline data analysis. - Users value the **real-time monitoring** of Nominis Vue, making it easier to detect risky transactions effectively. **Cons:** - Users express frustration with the **slow customer support** response times, impacting their overall satisfaction with Nominis Vue. ### 15.
