In-Depth Review TG4G Review ·2026-06-18 · For reference only

What It Is

CyStack was founded in 2017 and is a full-stack cybersecurity company headquartered in Vietnam. It combines proprietary technology platforms with the power of a white-hat community to provide Web2 and Web3 businesses with full-lifecycle security protection, from product development to long-term operations. It has served more than 600 enterprise customers to date.

Core Features (by Dimension)

  • Protection Types: Covers vulnerability scanning, penetration testing/red team–blue team exercises, endpoint security, password and secrets management, and blockchain security, creating a closed loop from prevention and detection to response.
  • Deployment: Primarily offers SaaS-based cloud tools such as VulnScan, while also supporting CLI and SDK integrations such as Locker Secrets Manager. Small and midsize businesses can complete deployment within 1–2 weeks.
  • Compliance Certifications: Holds ISO/IEC 27001, ISO 9001, and CREST penetration testing certifications, meeting strict enterprise compliance and standards requirements.
  • Management and Alerts: Provides centralized dashboard management through the CyStack Platform, with support for 24/7 real-time monitoring, risk detection, and alert response.
  • Integration Capabilities: Enterprise solutions integrate seamlessly with Jira, Slack, SSO, and SIEM. SDK support is available on the development side, enabling shift-left security.

Pricing

CyStack uses a tiered package model. Small and midsize businesses subscribe by tier, while large enterprises can obtain customized services. All commercial service packages currently include a free 1-year Locker Business license, but specific pricing requires contacting sales, so transparency is average.

Pros and Cons

Pros: A well-developed full-stack product ecosystem; highly efficient community-driven bug bounty testing; internationally recognized certifications and strong industry credibility; products that balance developer experience with operational security.

Cons: Pricing is not publicly available; brand reach is currently more concentrated in Vietnam and regional markets, and its global service capabilities still need further validation.

Who It’s For

Small and midsize businesses that need one-stop security management, as well as large enterprises with strict compliance and 24/7 monitoring requirements. It is especially suitable for teams involved in Web3 and blockchain businesses that need smart contract audits.
