Quick verdict.
Choose SealTask if encrypted content privacy matters more than broad project-management depth. SealTask may help with technical safeguards for regulated workflows. Before any PHI use, SealTask must expressly agree in writing. Where HIPAA applies, SealTask and the customer must execute a HIPAA-compliant BAA before use. Choose Asana if your team needs portfolios, goals, workload planning, forms, and automations, and you are comfortable with conventional SaaS access controls.

AI processing means workspace content may be processed when AI features are enabled or used; it does not mean customer data is used for model training.

Who should choose which?
Choose SealTask if...
- You handle sensitive client or internal project data
- You need strong encryption for regulated workflows
- You do not want server-side AI processing workspace content
- You prefer focused task management over a broad work OS
- You want the provider unable to read encrypted content
- You want a licensed self-hosted Docker option on your own hardware
Choose Asana if...
- You need advanced project and portfolio management
- Goals, workload planning, and timeline views matter
- Your team relies on forms, automations, and reporting
- Enterprise admin controls outweigh zero-knowledge encryption
- Your workflows are not centered on highly sensitive content
Security architecture.
SealTask: zero-knowledge.
SealTask encrypts readable workspace content on your device with ChaCha20-Poly1305 before sync. The client unlocks keys with an OPAQUE export key plus HKDF, and optional one-time backup keys stay user-held. The service does not hold the keys needed to decrypt that content; account and operational metadata remain server-visible.
Result: A database breach or legal demand can expose ciphertext and server-visible account, billing, security, audit, service, and workspace metadata. SealTask cannot decrypt readable workspace content without the client-held keys.
Asana: enterprise work management security.
Asana publishes encryption at rest and in transit, SOC 2 controls, Enterprise+ security options, and Enterprise Key Management for eligible customers. This is strong conventional SaaS security, but it is not zero-knowledge content encryption.
Result: Provider-side compromise or authorized access paths could expose plaintext content. Asana can process content for search, workflows, AI features, support, and lawful data requests where it is technically able to access that content.
Frequently asked questions.
Is Asana end-to-end encrypted?
No. Asana publishes encryption at rest and in transit, but not SealTask-style client-side end-to-end encryption. That means the service can process workspace content in plaintext for product features and authorized support workflows.
Can Asana employees see my data?
Asana publishes access controls and policies limiting employee access, but its architecture still permits authorized server-side access to workspace content. With SealTask's zero-knowledge architecture, even our engineers cannot access encrypted workspace content because we do not have the keys.
Does Asana use my data for AI training?
Asana publishes commitments that customer content is not used to train AI models. Its AI features can still process workspace content when enabled or used. SealTask cannot process encrypted workspace content with server-side AI because we cannot decrypt it.
Can I use Asana or SealTask for HIPAA-regulated PHI?
Do not treat either product as HIPAA-ready by default. SealTask's zero-knowledge design may help with technical safeguards. Before any PHI use, SealTask must expressly agree in writing. Where HIPAA applies, SealTask and the customer must execute a HIPAA-compliant BAA before use. Asana lists HIPAA compliance as available on eligible plans with requirements, including its Enterprise+ tier.
Which has more project management features?
Asana has broader work-management features, including portfolios, goals, workload planning, timeline and Gantt views, forms, and automations. SealTask focuses on encrypted task collaboration.
