From security snapshots to continuous coverage

Onchain systems evolve continuously, and the surface that needs to be secure runs well beyond the smart contract layer.

Point-in-time audits remain valuable, but they cover a slice of the system at a moment in time. Continuous coverage extends across architecture, infrastructure, governance, and operations, and stays in place as the system evolves.

Point-in-Time Security

  • A snapshot in a continuous world
  • Security validated at a single moment in time
  • Coverage gaps as systems and code evolve
  • Issues found late, expensive to remediate
  • Architecture, governance, operational risks out of scope
  • Each engagement starts from scratch

Continuous Security

  • Built for a continuous world
  • Continuous coverage across the full lifecycle
  • Feedback on every change, every commit, every upgrade
  • Issues caught early, when fixes are cheap
  • Architecture, governance, operational coverage included
  • Each engagement compounds on the last

What changes when security becomes continuous

A program shaped by the priorities of CISOs, heads of digital assets, and risk committees at financial institutions, and the security leads at the protocols redefining digital finance.

Risks caught at design stage

Catch architectural, governance, and operational issues at the design stage. Continuous coverage closes the gaps point-in-time audits leave open between engagements.

Predictable security spend

An annual engagement replaces unpredictable audit cycles, late-stage rework, and emergency engagements. Security planning aligns with the rest of your roadmap.

Faster time to market

Issues caught early are cheaper to fix and don't block launches. Audit readiness becomes a continuous state, not a project to scramble for before each release.

Audit-ready evidence base

An ongoing program produces the documented, auditable trail that risk committees, supervisors, and counterparties increasingly require.

Regulator and counterparty trust

Aligned with MiCA, DORA, Basel, GENIUS Act, and SOC 2. The kind of security posture you can defend in regulatory submissions and counterparty due diligence.

Security that scales with you

World-class researchers embedded in your roadmap. Institutional pattern recognition from 900+ engagements applied to your system, on top of your internal team.

Security across the full lifecycle, bundled around your needs

Delivered by world-class researchers and scaled continuously by OpenZeppelin AI, each engagement is tailored to your system's scale, complexity, and regulatory context.

“Our partnership with OpenZeppelin is critical. Their role extends far beyond traditional audits; they're embedded in our design process, our reviews, and our monitoring frameworks. Their deep expertise gives us the confidence to push boundaries, knowing that security will scale with us.”
— Vlad Bochok, Protocol & Security Engineer, Matter Labs
WisdomTree
“Bringing regulated funds onchain means security and compliance have to be inseparable, and they have to hold across every environment we build on. OpenZeppelin has been a continuous partner from architecture through deployment, across both our Ethereum and Solana work, and this consistency and rigor allows us to advance WisdomTree's tokenization roadmap confidently, at scale.”
