What It Is

DigiStamp is a trusted timestamping service provider built around RFC3161 TimeStamp Authority services. It is used to prove that a digital file or data hash existed at a specific point in time and has not been tampered with. Its positioning is closer to electronic evidence, digital signatures, and compliance-oriented record preservation infrastructure than to traditional firewalls, EDR, or vulnerability management tools.

Core Capabilities and Deployment

Its main security selling point is SecureTime: the site states that the clock is located inside an HSM, cannot be arbitrarily modified by system administrators, and only allows minor drift calibration. Timestamp signing runs inside FIPS 140-2 Level 4 tamper-resistant hardware. The cloud service offers 99.99% availability, with failover enabled through geographically distributed servers, AWS Global Accelerator, and load balancing. Deployment options are fairly broad, including a cloud TSA, browser application, API Toolkit, SecureTime Proxy, and purchasable on-premises SecureTime Server hardware.

Compliance, Integrations, and Management

On the compliance side, the main text explicitly mentions RFC3161, FIPS 140, eIDAS, and RFC6283, and lists legal compliance scenarios such as HIPAA, SOX, and CFR 11. Integration is a highlight: it supports Java, PHP, Linux Shell, OpenSSL, cURL, COM, and .NET/C#, and can also work with tools such as Adobe Acrobat, Microsoft Office, and BouncyCastle. Management capabilities are less clearly documented. The available information only mentions continuous monitoring of server utilization, and daily Proxy reports covering request volume, response time, and failed requests; there is no visible description of real-time alerts or SIEM integration.

Pricing, Pros, and Cons

Pricing information is incomplete. What can be confirmed is that the test server is free, the API Toolkit is free but timestamp transactions are charged, the Proxy software version is free with a one-year bulk contract, and the hardware device costs under 500 USD depending on contract volume. Its strengths are a high degree of specialization, open standards, and the fact that only hashes are transmitted rather than original files, making it suitable for systems that care about chain of evidence. The downsides are limited pricing transparency and a learning curve for ordinary users, who need to understand certificate chains, timestamp verification, and RFC3161.

Best Fit and Access from China

DigiStamp is better suited to enterprise developers, legal evidence preservation, intellectual property protection, high-frequency log certification, and the creation of government- or institution-level timestamp authorities. Access from China, payment methods, and local support are not disclosed in the main text and should be treated as unknown. If domestic compliance, invoicing, cross-border data transfer, or judicial admissibility is involved, Chinese local e-signature, timestamping, and judicial evidence preservation services should also be evaluated as alternatives.
