Acra

Acra is a data-protection platform for teams securing sensitive information in databases and applications. It suits developers and security teams that need encryption close to their data and control over deployment. Its mix of database proxies, APIs, and SDKs is compelling, but the Community Edition’s narrower feature set makes enterprise use a paid decision.

Overview

Acra protects sensitive data in SQL and NoSQL databases, web applications, and backend applications. Rather than requiring one integration pattern, it can sit in the database path as a transparent SQL proxy, serve encryption through HTTP or gRPC APIs, or be used through client-side SDKs. That flexibility helps teams adapt protection to existing systems, though it also means the right fit depends on how an application handles data.

Key features

Acra supports field-level and searchable encryption, tokenization, and data masking. Those options address different needs: field-level encryption protects selected values, searchable encryption supports queries over protected data, and masking or tokenization can limit exposure in application flows. The Community Edition includes encryption and masking, but its single configuration policy is a constraint for teams that need broader policy management.

AcraServer supports PostgreSQL and MySQL wire protocols, including MySQL 5.7+, PostgreSQL 9.4+, and MariaDB 10.3. The Community Edition does not support MySQL Protocol X, so teams relying on that protocol should consider Enterprise or another solution. The maker also identifies MongoDB, Redis, Cassandra, and TimescaleDB among supported NoSQL and key-value stores.

For key storage and management, integrations include Amazon KMS, Google Cloud KMS, HashiCorp Vault, Keywhiz, and HSMs. Acra can detect requests for planted poison records or honeytokens, raise alarms, and halt decryption. Its security logging supports SIEM/SOC analytics, while a crypto-signed audit log records access and security events. These capabilities make it more than an encryption layer for teams that need detection and audit controls alongside data protection.

Pricing

Acra Community Edition is free, billed FREE and free forever for non-profit and business use. It includes encryption and masking, an SQL request firewall, basic intrusion detection, and one configuration policy. The no-cost plan makes prototyping and small-scale projects practical, but lacks the full feature set and policy management of Enterprise.

Acra Enterprise Edition starts at $10,000 a year, billed starting at $10000 annually. Pricing depends on the number of deployments and requested features. It includes all Acra features and controls, policy management, DevOps/SRE tooling, and various support tiers. This is the relevant tier for large-scale deployments that need broader controls or support, but its starting price is a substantial commitment.

Acra bespoke solution has custom pricing based on included services and case-by-case requirements. It covers customized masks and protocols, tailored behavior and use-case-specific features, plus engineering and architecture support. That option is for requirements the standard editions do not cover, rather than teams seeking a predictable subscription.

A free evaluation playground running Acra Enterprise Edition is offered for selected popular use cases, giving teams a way to assess enterprise scenarios before committing.

Platforms

Acra is available for Android, iOS, Linux, API use, and self-hosted deployment. Server components run on Linux distributions including CentOS, RHEL, Debian, and Ubuntu; Docker images and Kubernetes-compatible images support containerized deployments. The service is described as cloud-agnostic and actively tested and supported on Google Cloud Platform, AWS, and DigitalOcean.

Windows is supported for clients connecting to Acra on a Linux server, but server-side Acra components should not run on Windows as the host operating system. Teams that require a Windows-hosted server should look elsewhere.

Who it's for

Acra is best suited to development and security teams protecting sensitive database fields across varied application architectures, especially when they need external key-management integrations, audit trails, or intrusion detection. Community Edition is positioned for prototypes and smaller projects; Enterprise is the intended fit for large-scale and enterprise deployments. Multiple support tiers include integration assistance, solution support, and 24/7 solution support.

Pros and cons

• Multiple integration patterns: A SQL proxy, HTTP/gRPC API, and client SDKs let teams choose how protection fits their application architecture.
• Broad security controls: Encryption choices, masking, key-management integrations, planted-record detection, and signed audit logs cover more than basic data encryption.
• Useful free entry point: Community Edition is free forever for business and non-profit use, but one policy and the MySQL Protocol X exclusion limit its reach.
• Enterprise cost: Enterprise starts at $10,000 a year, which may be difficult to justify for smaller deployments.
• Linux-only server hosting: Windows clients can connect, but Windows cannot host server-side Acra components.

Alternatives

Cloud Encryption Software is a useful category starting point for comparing options.

• Thales CipherTrust Data Security Platform is worth considering if a free community edition and free trial are priorities; it supports API, Linux, self-hosted, and web platforms.
• Protegrity Data Security Platform is another freemium option, with web platform support.
• Cosmian Data Protection Suite may suit teams seeking a paid KMS with per-CPU pricing, all connectors included, and any number of servers; it offers a free trial.
• Cryptomator is a freemium alternative that describes itself as open source, with source code publicly available for community security audits.
• Ubiq Security is a paid API, self-hosted, and web option.
• Baffle Data Protection offers a 30-day free trial for cloud data masking in lower environments, with PostgreSQL source and target hosted in AWS.
• Skyflow is a paid option with a free trial and support for Android, API, iOS, self-hosted, and web platforms.
• Confidencial is another paid, web-based alternative.

Verdict

Choose Acra if your team needs flexible, self-hosted protection for sensitive database data, with a free edition for smaller projects and a fuller enterprise tier for scaled deployments. Its strongest case is the combination of deployment patterns, encryption choices, key integrations, and security monitoring. Look elsewhere if Windows server hosting is essential, MySQL Protocol X is required on the free tier, or Enterprise pricing is beyond your budget.
