Encrypted, searchable data?
You better believe it.
CipherStash does the hard work to make securing your sensitive data easy.
Built from the ground up to be secure, fast and easy to use.
Sign up for freeA new kind of data storage platform
When your code interacts with the CipherStash Data Platform, every query, insert and update is encrypted before it is sent across the network - and it is done so with keys that you control. This means that sensitive data is always protected but you can still search it using the kinds of queries you're familiar with.
Trailblazing encryption, in your hands
Where you store data matters
Whether it's in a traditional SQL database, a NoSQL store or search index, where and how you store sensitive data is paramount to keeping it secure. If data security is important to you then you probably already use encryption of some form or another but it might not be as secure as you think.
The Problem
Transparent Data Encryption
Transparent Data Encryption (TDE) is a common approach that encrypts the underlying filesystem of your database. Clients can access data as normal but TDE offers only limited protection because in a running database, everything is decrypted.
Database records encrypted directly
One alternative is to encrypt every column and row in your database. While this offers good levels of security the ability to perform useful queries either disappears entirely or comes with major trade-offs. Records can only be retrieved by an unencrypted (or deterministic) primary key.
The Solution
CipherStash
CipherStash uses a searchable encryption scheme that means data is always encrypted (including field names) but remains searchable by clients with the appropriate key. Even the queries themselves are encrypted! This gives your sensitive data very high-levels of protection without compromising on usability.
Built from the start for security
CipherStash was designed from the start to meet very high-levels of security and compliance. Instead of building on top of existing relational-databases or search indexes (which have major security drawbacks, even when encrypted), CipherStash uses a fast, memory-mapped B-tree and an Order-Revealing Encryption scheme based on research from Stanford University.
Based on Industry Standard Cryptography
CipherStash is based on existing primitives like AES and SHA-256. It's actually kinda boring! But that means there is less to go wrong.

CipherStash is resistant to "snapshot attacks" where an attacker can get a copy of your entire database system - including files, logs and a copy of all running memory.
AWS: Your account or ours?
CipherStash runs in AWS and allows you to host parts of the infrastructure in your own account.
Next generation authentication
Say goodbye to credentials in connection strings! Connect to CipherStash using flexible, secure auth schemes that don't require you to reinvent the wheel.
Your Application
Any NodeJS application can use CipherStash. Other languages and frameworks coming soon.
Authenticate
Your app authenticates to a supported Identity Provider. You can use your existing IdP or the one hosted by CipherStash. Both user and machine-to-machine flows are supported.
Supported Providers
More integrations coming soon
Encryption Service
Both documents and queries are encrypted (and decrypted) using the encryption service. We can fully manage for you (still with keys that you control) or you can manage the whole thing yourself (coming soon).
Data Service
Documents are stored in the end-to-end, searchable encrypted data store which can then be queried with fully encrypted queries.
The Data Service is fully managed in the CipherStash cloud but never sees any data in the clear.
Text search over encrypted data
Partial or Exact Matches
CipherStash allows you to perform text searches over your data set with close to the performance of traditional data stores. Both the queries and the replies are encrypted end-to-end.
// Partial string match
await customers.all(
customer => customer.name.match("Ada")
)
// Exact ("keyword") match
await customer.all(
customer => employee.status.eq("active")
)Range queries over encrypted data
Range Queries
Fetch all records that match a range condition such as integers greater than x or records before a timestamp.
// All customer signed up in the last 30 days
let monthAgo = new Date() - DAYS_30
let results = await customers.all(
customer => customer.signedUpAt.gte(monthAgo)
)Combinations!
Combine query types
Combine constraints on multiple fields or compose queries for great flexibility.
// All full-time employees paid over $100k
let results = await employees.all(
employee =>
all(
employee.salary.gt(100000),
employee.employment.eq("full-time")
)

All the mod cons
Standard serialisation formats
CipherStash uses industry leading serialisation formats to reduce attack surface to mitigate attacks like:
Injection attacks
Stops data injection by strictly only supporting primitive data types
Privilege escalation
Stops attackers gaining Remote Code Execution through object deserialisation
Denial of Service attacks
Stops resource exhaustion by strictly dropping and logging badly formatted requests
Industry leading authentication
Say goodbye to credentials in connection strings!
CipherStash is built with industry leading third party identity providers, with a zero trust model, to mitigate vulnerabilities like:
Broken authentication
Limit impact of compromised credentials and account takeovers — involved in 20% of all breaches
Broken access controls
Limit privilege escalation, through strictly scoped credentials.
TLS everywhere
Take transport layer security to the next level by terminating in the database itself, mitigating attacks like:
Sensitive data exposure
Queries are encrypted, and encrypted again on the wire to and from CipherStash
Injection attacks
Responses are encrypted on the wire to stop attackers interfering with your query responses.
Replay attacks
CipherStash strictly uses Forward Secrecy ciphers (ECDHE, DHE) with TLS >=1.2 to ensure compromised keys don’t result in total data exposure.
