Ankr vs Chainstack: ISO 27001 Certification Status

Chainstack excels at providing a certified, audited security framework for enterprise clients. It holds an ISO 27001:2013 certification, a globally recognized standard for information security management systems (ISMS). This formal certification is a non-negotiable requirement for projects in regulated sectors like DeFi, institutional finance, and enterprise blockchain integrations, where demonstrable compliance is mandatory for vendor selection and risk management.

Ankr takes a different approach by prioritizing a broad, multi-chain infrastructure and developer experience, with its security posture built on SOC 2 Type II compliance and a 99.9% uptime SLA across its RPC services. While robust, this strategy results in a trade-off: it lacks the formal, externally audited ISO 27001 certification that serves as a universal security benchmark for large enterprises and financial institutions evaluating long-term infrastructure partners.

The key trade-off: If your priority is formal compliance and audited security controls for regulated applications or enterprise procurement, choose Chainstack. If you prioritize maximum chain coverage, high-performance RPCs, and a developer-first ecosystem for a product where SOC 2 meets internal security requirements, Ankr presents a powerful alternative.

Chainstack excels at providing a formal, audited security framework for enterprise clients because it holds a current ISO 27001:2013 certification. This globally recognized standard for Information Security Management Systems (ISMS) provides a concrete, third-party-verified assurance of their security controls, data protection, and risk management processes. For a CTO managing a $500K+ infrastructure budget, this certification directly addresses compliance requirements for regulated industries like DeFi (e.g., Aave, Compound) or institutional custody solutions, reducing vendor risk and audit complexity.

Ankr takes a different approach by prioritizing a broad, decentralized node network and developer tooling like its RPC Service and App Chains. Their public documentation and marketing emphasize security best practices and infrastructure resilience, but they do not currently advertise an active ISO 27001 certification. This strategy results in a trade-off: potentially faster innovation and a wider array of blockchain protocols supported, but without the same level of formal, standardized security attestation that large enterprises often mandate for core infrastructure dependencies.

The key trade-off: If your priority is regulatory compliance, enterprise procurement requirements, or mitigating third-party risk for high-value applications, choose Chainstack. Its ISO 27001 certification is a non-negotiable asset for projects in traditional finance (TradFi) bridging to blockchain or protocols with strict governance. If you prioritize protocol diversity, decentralized infrastructure, and rapid prototyping across a vast ecosystem (including Avalanche, Polygon, Sui), and your internal security team can perform due diligence, Ankr's extensive network and tools may offer greater flexibility.
