Security at Phase
Access to your secrets is controlled by encryption keys that only you hold. Phase is built on a rigorous cryptographic foundation: open source, end-to-end encrypted by default, and engineered for enterprise-grade security.
SOC 2 Type 2
Independently audited by Oneleet. Our controls are examined continuously. Audit reports are available in our trust center.
Penetration tested
Penetration tested by Oneleet, an independent security firm, across the platform, APIs and services, with remediation tracked to completion. Executive summaries are available through the trust center.
OpenAI Daybreak
Phase is an OpenAI Daybreak partner.
Daybreak is OpenAI's cyber defense program. It gives verified defenders governed access to GPT Cyber models, with scope controls, monitoring and human review.

Crypto.
One standardized set of primitives across the platform: elliptic-curve cryptography on Curve25519, authenticated encryption, and memory-hard key derivation. All implemented using the open source libsodium library.
ChaCha20
CSPRNG — crypto_kdf_keygen · 32-byte keys seeded from /dev/urandom · crypto.getRandomValues()
XChaCha20-Poly1305
AEAD — 256-bit keys · 192-bit nonces · per-field ephemeral keypair + random IV · output K_eph ‖ C ‖ IV
X25519
ECDH over Curve25519 — 256-bit keys · ephemeral keypair per operation → session key
XOR · t = n
2-of-2 split of a 256-bit key — share0 ⊕ share1 · an individual share reveals nothing
Argon2id
Memory-hard — 32-byte seeds · account seed: 1 GB · 4 iterations · device key: 64 MB · 2 iterations
Blake2B
crypto_kdf_derive_from_key — CONTEXT __sign__ → Ed25519 signing keys → X25519 · key digests salted with Salt_env, 32-byte outputs — server-side lookups without plaintext
End-to-end encryption
Encrypted by default: keys, values and comments, with an independent key for every environment. In the default E2EE mode Phase servers store only ciphertext and cannot decrypt your secrets.
Your account keys derive from a 24-word mnemonic phrase only you hold. Granting access wraps an environment’s keys to your account’s public key. The server stores wrapped keys and ciphertext it cannot open.
End-to-end encryption is the default. Server-side encryption is a per-app opt-in for when you need third-party syncs or the REST API. The environment key is then stored encrypted on the server.
Share a secret with anyone via a single link: the Box Seed travels in the URL fragment, parsed only by the browser and never sent to the server. View limits and expiry built in.
