Sendtry
From brief to shipped
Requirements, client documents, approvals, and delivery issues in one workspace. Software lifecycle without the noise.
Flagship · encrypted secret sharing
Built for the agent era.
Agents and teammates need credentials — not plaintext in Slack, logs, or prompts. SharePassword encrypts secrets client-side so keys move as expiring links, with least privilege for whoever opens them.

Credential hygiene & secret sharing
How secrets move between people and systems — client-side encryption, expiring links, and least-privilege defaults operators actually use. Foundation for safer cloud and agent workflows.
- Client-side encryption for passwords, keys, and files
- One-time and expiring share links
Agent riskLLMs follow instructions. Attackers write them too.
Prompt injection & agent abuse
In the agent era, prompt injection and tool abuse are first-class threats. We design controls, isolation, and review loops so agents help without becoming a backdoor.
- Prompt injection patterns against tools & data
- Least privilege for agent credentials and tools
PracticeYour API is the product’s attack surface.
API security & exposure
API vulnerability and abuse analysis — authZ gaps, over-permissioned tokens, data leakage paths, and rate/abuse controls — so product APIs stay an advantage, not a liability.
- AuthN/AuthZ and token scope review
- Exposure, IDOR-class, and data-leak paths
