Encrypt Everything: Zero-Trust at the Agent Data Layer
Traditional AI security relies on network-layer firewalls and prompt filtering
Autonomous agents have persistent memory, shared context, and enterprise database access
Perimeter defense alone cannot protect agentic AI systems
NuDay encrypts the agent data layer itself - the agent's brain
Industry's first Encryption-First Agent Security Platform with Post-Quantum Cryptography
If attackers breach your network, agentic workflows remain mathematically unbreakable
What NuDay Encrypts
Unlike traditional agentic solutions that leave AI agent memory sitting in plaintext, NuDay enforces real-time, zero latency, end-to-end cryptographic protection across the entire cognitive lifecycle of your agents.
1. All Saved Agent Inputs & Prompts
The Vulnerability
Standard Agentic AI solutions store user prompts and system inputs in plaintext, exposing sensitive business context and PII.
The NuDay Standard
Every prompt, instruction, and contextual input fed to the agent is encrypted before it is stored or logged. Your proprietary business logic remains confidential, satisfying strict data minimization requirements for GDPR and CCPA.
2. Searchable Agent History
The Vulnerability
Autonomous agents need to remember past actions to complete complex tasks, but storing execution logs in standard databases creates a massive compliance liability.
The NuDay Standard
We encrypt the agent's long-term operational history while utilizing advanced cryptography that keeps it vector-searchable. The agent can query its own past experiences via similarity search, but a human attacker accessing the database will only see randomized ciphertext.
3. RAG Data (Retrieval-Augmented Generation)
The Vulnerability
Vector databases (like Postgres pgvector or Pinecone) are frequently left exposed, acting as a honeypot for unstructured enterprise data, source code, and PHI.
The NuDay Standard
NuDay encrypts your proprietary enterprise data before the embedding model chunks and stores it. When your agent queries the RAG pipeline, the retrieval and decryption process happens in real-time automatically, governed by the agent's access keys.
4. Shared Agent Memories (A2A Context)
The Vulnerability
In multi-agent systems, agents pass sensitive context back and forth. If this internal communication is unencrypted, one compromised low-level agent can scrape the memory of a high-privilege agent.
The NuDay Standard
NuDay enforces encrypted, mutual authentication (mTLS) for all Agent-to-Agent (A2A) communication. Shared memory workspaces are cryptographically segmented so that only verified, participating agents can decrypt the collaborative context.
5. The Agent Core: Identity, Tools, and Guardrails
The Vulnerability
Adversaries use prompt injection to trick agents into ignoring their safety instructions or executing unauthorized backend tools.
The NuDay Standard
We lock down the agent's identity and capabilities via Cryptographic Signatures. Tools & Skills: An agent cannot execute a tool unless the command carries a verified public/private key signature. Guardrails & Guidelines: Anti-bias rules and behavioral limits are cryptographically bound to the agent. They cannot be bypassed, rewritten, or "forgotten" during runtime.
Realtime Agent Encryption
-
Agent Action
reply, memory, or tool call
It starts with the agent.
A reply is generated, a memory saved, a tool called - producing a fresh checkpoint of state.
- Agent config validated
Signed config verified before every turn.
- 01
CHK2 checksum
plaintext integrity
Detect corruption.
A digest of the plaintext rides in a versioned header and is re-verified after every decrypt.
- 02
SIG1 signature
classical or post-quantum
Prove authorship.
Classical DSA or post-quantum ML-DSA (Dilithium), per tenant. Going PQ is a config switch.
- 03
AES-GCM encrypt
epoch-derived key
Seal the record.
Authenticated encryption under a key unique to this checkpoint: epoch root key, XOR version chain.
- Automatic key rotation
Fresh root keys arrive on whatever schedule you set.
- 04
HMAC + headers
MAC over payload + epoch
Verify independently.
A keyed MAC over payload + epoch adds a second integrity layer with an independent key.
- 05
Store sealed blob
written to state database
Nothing readable at rest.
A stolen database yields only ciphertext; tampering is caught on load and alerts fire immediately.
State database
every message its own encrypted, signed, tamper-evident record
Layer-by-layer cryptographic breakdown for technical readers
Keys that rotate themselves
Root keys are scoped per epoch and per tenant. A control-plane rotation job advances the epoch automatically on a configurable cadence, so the blast radius of any single key is minutes of data, not a database. Tenant scoping means a per-tenant revocation affects exactly one tenant - and the agent cannot even start its secure saver unless the NuDay Manager control plane answers its heartbeat.
Why it matters
Most agent frameworks persist conversation state as plaintext JSON. NuDay makes every message its own cryptographic domain: four independent protections per record, per-message keys, scheduled rotation, tenant isolation, and optional post-quantum signatures - provider-agnostic, in the cloud or fully on-premises. A database compromise yields nothing readable; tampering announces itself.
Future-Proofed: Post-Quantum Cryptography & Native Crypto-Agility
The threat landscape is rapidly shifting toward a "Harvest Now, Decrypt Later" model, where nation-state actors steal encrypted data today to break it with tomorrow's quantum computers. NuDay secures your autonomous infrastructure against both current and future threats.
Post-Quantum Cryptography (PQC)
We natively support NIST-approved post-quantum algorithms (such as ML-KEM and ML-DSA), ensuring that your agent's memory, RAG stores, and A2A communications are immune to quantum decryption.
Native Crypto-Agility
Enterprise compliance is a moving target. NuDay's architecture is completely crypto-agile. As cryptographic standards evolve, your security team can hot-swap encryption libraries and key management protocols with zero downtime and without rewriting a single line of your agent code.

Encryption Details
CHK2 - plaintext checksum
A configurable hash (SHA-256 by default) is computed and prepended in a versioned header, then re-verified against the decrypted payload on every load - corruption and partial writes are caught immediately.
SIG1 - digital signature
Classical DSA or post-quantum ML-DSA (Dilithium), selectable per tenant. Post-quantum readiness is a configuration switch, not a migration project.
AES-GCM - authenticated encryption
A 12-byte random nonce, and a key that is unique per checkpoint: derived from the current epoch root key and XOR-chained with the previous version. No two records ever share a key.
HMAC - independent integrity
A keyed MAC over the payload plus epoch number, verified before decryption. Combined with GCM's own tag, integrity is enforced at two independent layers with independent keys.
Store - the sealed record
What lands in the state database is unreadable without the control plane, and any tampering is detected the moment it is loaded. Verification failures alert operators in real time.
