Chainstack achieved SOC 2 Type II certification

We are proud to announce that as of December 22, 2025, Chainstack has officially achieved SOC 2 Type II certification!

This milestone marks a new high standard in our ongoing commitment to security and trust. By completing the rigorous Type II audit, Chainstack reinforces its promise of providing secure, reliable blockchain infrastructure for all users and enterprises.

In this blog post, we’ll explore what SOC 2 Type II means, how the audit works (with a focus on security, availability, and confidentiality), why this certification matters for blockchain infrastructure providers, and the key benefits it brings to our customers.

What is SOC 2 Type II certification?

SOC 2 stands for System and Organization Controls 2, a security and compliance framework developed by the American Institute of CPAs (AICPA). It defines how service organizations should manage customer data based on five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy. In essence, SOC 2 is an independent auditing procedure that ensures a service provider (like Chainstack) securely manages data to protect client interests.

Importantly, SOC 2 reports come in two types. A Type I report evaluates the design of a company’s security controls at a single point in time. In contrast, a Type II report assesses how well those controls operate over a period of several months (typically 3–12 months). In other words, Type II goes beyond a snapshot; it proves that security measures aren’t just in place, but consistently effective in practice.

According to industry guidance, a SOC 2 Type II offers greater assurance to customers, often regarded as the gold standard for demonstrating robust security and reliability. Achieving SOC 2 Type II certification means an independent auditor has thoroughly reviewed Chainstack’s systems and processes over time and found that we meet the stringent criteria for protecting customer data and maintaining service excellence.

What the SOC 2 Type II audit evaluates (security, availability, confidentiality)

A SOC 2 Type II audit entails a comprehensive examination of our internal controls across the chosen Trust Services Criteria. Security is always included in every SOC 2 audit, and for an infrastructure provider like Chainstack, availability and confidentiality are also critical focus areas. Here’s what each of these principles means and how they’re evaluated:

• Security: Security focuses on protecting system resources from unauthorized access. During the audit, an independent auditor reviews how we control access to systems, prevent data breaches, and ensure that only authorized personnel can interact with sensitive information. At Chainstack, this includes role-based access control (RBAC), multi-factor authentication for users and internal teams, as well as encryption and firewalls to protect data. These controls help prevent data alteration, theft, or misuse and ensure our infrastructure remains resilient against security threats. Meeting the Security criteria demonstrates that customer data and operations are well protected from unauthorized access.

• Availability: Availability evaluates whether systems and services remain reliable and accessible as promised, including compliance with uptime commitments and service level agreements. The SOC 2 audit reviews how we maintain uptime, respond to incidents, and recover from disruptions. Chainstack’s globally distributed infrastructure and redundancy planning are designed to minimize downtime, even during adverse events. We use continuous monitoring, automatic failover, and regular backups to keep services running reliably. As a result, Chainstack consistently delivers enterprise-grade availability with 99.99%+ uptime.

• Confidentiality: Confidentiality focuses on protecting sensitive data from unauthorized disclosure. The audit assesses how we restrict access to data, apply encryption, and enforce data handling policies. At Chainstack, all sensitive data at rest is encrypted using strong standards such as AES-256, and data in transit is protected with TLS encryption. Access to customer information is limited to authorized personnel only, and data that is no longer required is securely erased. By meeting the Confidentiality criteria, Chainstack ensures that private keys, transaction data, and other sensitive information remain secure and accessible only to the appropriate parties.

It’s worth noting that a SOC 2 report can cover additional criteria like Processing Integrity and Privacy. Chainstack’s audit was comprehensive – addressing all five Trust Service Criteria in our controls – but security, availability, and confidentiality were especially pertinent given our role as a blockchain infrastructure provider. The audit process involved an accredited CPA firm scrutinizing our controls in these areas over several months, verifying not just that we have documented policies, but that we consistently follow them in daily operations. Passing this audit with flying colors means our safeguards in security, uptime reliability, and data protection are not only well-designed but also proven effective through real-world observation.

Why SOC 2 Type II certification matters for blockchain infrastructure

In the cloud and blockchain infrastructure industry, trust is paramount. Enterprises and developers rely on infrastructure providers to handle critical transactions, sensitive keys, and high-value data. Obtaining a SOC 2 Type II certification sends a strong signal that Chainstack meets an industry-leading standard of security and operational maturity. In fact, many security-conscious businesses now treat SOC 2 compliance as a minimal requirement when choosing a SaaS or cloud provider. This is especially true in finance, enterprise, and regulated sectors that are increasingly embracing blockchain technology.

For blockchain infrastructure providers, the stakes are even higher. The decentralized nature of Web3 doesn’t eliminate the need for trust in the platforms that enable access to blockchain networks. By achieving SOC 2 Type II, Chainstack demonstrates to our customers and partners that we have been independently verified to uphold strict security controls, high availability, and confidentiality of data. This certification differentiates Chainstack in the Web3 ecosystem, showcasing our commitment to enterprise-grade best practices. It also aligns us with other top-tier infrastructure providers that have invested in compliance – essentially raising the bar across the industry. As a result, current and prospective customers can have increased confidence that Chainstack’s platform is built on a foundation of audited, trusted processes.

SOC 2 Type II is often called a gold standard for assurance, and for us it’s a means to foster greater trust in blockchain adoption at the enterprise level. Whether you are a startup developer or a large financial institution building on Chainstack, you know that our security and reliability claims aren’t just marketing – they are validated by a reputable third-party audit.
