Your manuscript, protected end-to-end

Built on Google Cloud infrastructure with the same encryption, DDoS mitigation, and compliance posture trusted by YouTube, Gmail, and Spotify. Your work in progress stays yours.

Your chapters, your translations, your AI prompts — encrypted at every layer so you can focus on writing, not security.

Your manuscript is encryptedEnd-to-end AES-256
Every chapter, footnote, image, and AI prompt is encrypted at rest (AES-256) and in transit (TLS 1.3). Nobody can read your work in progress, not even us.
Protected from attacksWAF + DDoS mitigation
Books and exports are shielded by Google Cloud Armor, which automatically blocks SQL injection, XSS, and DDoS attacks before they reach your content.
Credentials never exposedYour keys stay safe
API keys, Paddle subscription tokens, and OAuth credentials are never stored in plain text. They live in isolated vaults so even if our codebase were compromised, your account stays safe.
Built on Google CloudSOC 2 · ISO 27001
Your manuscripts run on the same Google Cloud infrastructure trusted by YouTube, Gmail, and Spotify. Certified SOC 1/2/3, ISO 27001, ISO 27017, and PCI DSS.
Always HTTPS securedAuto-renewing SSL
Every connection to your books is encrypted with TLS 1.3 and Google-managed SSL. HTTP requests auto-upgrade to HTTPS — no setup, no expiring certificates.
OWASP Top 10 hardenedIndustry-standard audits
CMSCure Books is continuously hardened against the OWASP Top 10, the industry standard for web application security, so your account stays vulnerability-free.
99.99% uptimeWrite whenever inspiration strikes
Your editor, exports, and AI features run through a global load balancer with automatic failover and health checks. If one server has issues, traffic instantly reroutes.
Abuse-proof APIsRate limiting built-in
AI tokens, exports, and account actions are protected by multi-layer rate limiting — blocks brute-force attacks, credential stuffing, and bot abuse so your token allowance is never burned by someone else.

Your manuscript is hosted on Google Cloud Platform, the same infrastructure trusted by YouTube, Gmail, and Spotify. Every save is encrypted with TLS 1.3, every API call is rate-limited, and your AI token allowance is protected against abuse. You own everything you write — CMSCure does not retain rights to your manuscript or AI-generated content.
