What Solidified does

Solidified is a Web3 cybersecurity services firm operating as a brand of Oak Security GmbH, a Munich-registered private limited company. The company provides smart contract audits, security strategy workshops, threat modeling, and Virtual Chief Security Officer (vCISO) services to enterprise blockchain protocols and DeFi platforms, including the Ethereum Foundation, Arbitrum, and projects in the Solana ecosystem.

Its core audit offering is differentiated by a blinded competitive process in which top contest winners and security researchers compete on each engagement, with a performance-based fee structure in which missed critical issues trigger a return of the auditor's bonus. The vCISO add-on extends this into ongoing managed security leadership covering secure development workflows, incident readiness, DevSecOps coaching, and internal reviews under a shared-responsibility framework, deliberately positioning the firm against the one-time audit model prevalent in crypto security.

Commercially, Solidified runs a bespoke enterprise field-sales motion with quote-based pricing, multi-year contracts, and discovery calls led by the leadership team. Its distribution is direct-to-enterprise and global, supported by GDPR/CCPA compliance, PR-led thought leadership, and a website funnel. The firm is founder/management-controlled, with only $620K of disclosed external funding raised in 2017–2018, and operates with an 11–50 person delivery team.

Core offering

Solidified provides cybersecurity services for Web3 and blockchain projects, with a core focus on smart contract audits delivered through a proprietary Blinded Audit Process in which top contest-winning auditors compete against each other and face financial penalties if critical issues are missed. Beyond audits, the company offers Virtual Chief Security Officer (vCISO) services that embed ongoing security operations guidance, secure development workflows, incident readiness, DevSecOps coaching, and internal reviews into client teams. All engagements are bespoke, supported by security strategy workshops and threat modeling, and are backed by a shared-responsibility framework rather than one-off audit deliverables.

Product overview

Solidified is a cybersecurity services company for Web3 that offers a unified platform combining smart contract audits with value-added security services. The core product is its competitive smart contract audit process featuring blinded evaluator selection and financial incentives tied to quality. This core audit service is supplemented by a Virtual Chief Security Officer (vCISO) module for ongoing security operations guidance, and security strategy workshops with threat modeling — all designed to embed security throughout the client organization's development lifecycle rather than treating security as a one-time deliverable.

Functional benefit

Products and services

• Smart Contract Audits Security audits for Web3 protocols delivered through a proprietary Blinded Audit Process in which top contest-winning auditors and researchers compete against each other; if critical issues are missed, a significant portion of Solidified's fee is returned from the auditor's performance bonus. Targeted at blockchain protocols, DeFi platforms, and smart contract ecosystems that require rigorous, accountable code review.
• Virtual Chief Security Officer (vCISO) Retainer-style engagement that provides Web3 teams with executive-level security operations guidance without a full-time CISO hire, covering secure development workflows, incident readiness, DevSecOps coaching, and internal security reviews.
• Security Strategy Workshops and Threat Modeling Bespoke workshops and threat modeling engagements tailored to each Web3 client's protocol, pipeline, and threat profile to strengthen the client's overall security posture and attack-surface awareness beyond point-in-time code review.

Direct peers

• OpenZeppelin: OpenZeppelin provides smart contract security audits, secure libraries, and security tooling for Ethereum and EVM-compatible chains. It is a direct competitor in the protocol-audit market, including recurring services and developer-grade security products, and shares Solidified's Ethereum Foundation / Arbitrum adjacency.
• CertiK: CertiK is one of the largest smart contract auditing and blockchain security firms, offering audits, formal verification, and a security leaderboard scoring product. It competes head-on with Solidified for protocol audit mandates but at significantly greater scale, with both a service and a tooling/marketplace component.
• ChainSecurity: ChainSecurity is a smart contract auditing firm rooted in academic research, known for formal verification and Ethereum Foundation-adjacent work. It targets the same protocol and DeFi customer base as Solidified with a similarly high-touch, expert-led audit model.
• Trail of Bits: Trail of Bits is a leading independent cybersecurity firm specializing in blockchain and smart contract audits for protocols, DeFi, and cryptographic systems. Directly comparable because they target the same Web3 protocol clients with bespoke, talent-led audits and similarly serve Ethereum-layer and major L2 ecosystems where Solidified is active.
• ConsenSys Diligence: ConsenSys Diligence is the smart contract auditing arm of ConsenSys, focused on Ethereum and EVM-compatible protocols. It shares Solidified's protocol-side buyer and Ethereum-ecosystem positioning and is one of the most established competitors in the smart contract audit niche.
• Sigma Prime: Sigma Prime is a boutique blockchain security consultancy specializing in Ethereum, consensus layer, and smart contract audits. It overlaps with Solidified in serving the Ethereum Foundation ecosystem and in being a researcher-led boutique rather than a scale-auditor.
• Quantstamp: Quantstamp provides smart contract security audits and formal verification with an emphasis on automated tooling and continuous monitoring. It competes with Solidified for the same Ethereum/L2/DeFi protocol client base and offers a software-augmented alternative to the pure-services model.

Emerging players

• Zellic: Zellic is a smart contract and blockchain security firm founded by academic researchers and CTF winners, offering Web3 audit services and tooling. It mirrors Solidified's talent-winner narrative while building a more recent, scaling brand that competes for the same protocol audit work.
• Spearbit: Spearbit is a security services network that aggregates elite independent smart contract auditors under a curated brand. It overlaps with Solidified's talent-led, contest-winner-driven positioning but operates as a marketplace/network rather than an in-house audit firm.

Others

• Oak Security GmbH: Oak Security GmbH is Solidified's parent entity, the Germany-based Web3 cybersecurity firm from which Solidified was spun off in November 2025. It is included as an "other" because it is the parent rather than a true peer, but it shares the same auditor talent pool and customer base and remains a relevant comparison point for capability overlap.
