We're here to guide you for as long as needed.

What we cover in your migration session

Bring the policies you are least sure how to move. We work through them with you, live, and show what the move means for each team.

check-mark

Your Polar policies in Cerbos. See a few of your policies translated, with their tests passing and your authorize, list and list_local calls mapped across.

check-mark

No second copy of your data. Map each fact Oso holds to data you already have, so the dual writes and the sync job go away.

check-mark

Decisions and evidence you control. Keep every decision inside your network, with audit logs that name the policy behind each one.

check-mark

A move with no big bang. Plan how to run Cerbos beside Oso and switch over one part of your application at a time, so users and the roadmap carry on as normal.

check-mark

Permission changes without a release. Walk through how product and security teams change roles and tenant rules as reviewed policy updates, not application deploys.

check-mark

Effort, timeline and pricing. Get a rough effort estimate for your team, and see what evaluation, proof of concept support and pricing look like.

Not ready for a call?

Read the step by step migration guide, with a worked Polar translation, or compare the two products in Cerbos vs Oso.

Authorization management platform

Why teams love Cerbos

Chuck Hardy company logo

"When I did an audit, I found that the cost of managing authorization and authentication in-house over the entire lifespan of the company was in the 7 figures. Cerbos saved that. Deploying Cerbos has allowed our engineers to spend their time on what really matters for our success."

"Having to modify authorization is a five-minute job now. Having to troubleshoot authorization is a five-minute job. So that has actually allowed the team to spend more time where it really matters on the platform."

"We went from one user - every role, to a world where there are many users - many roles. And the product, it relies on Cerbos to actually bring the value that we want to bring to customers. All of our customers are relying on Cerbos, by relying on the product, which is of course relying on Cerbos."

"One of our big considerations was speed. We have strict latency tolerances. When it comes to Cerbos - you can call it a hundred times during a request and it doesn't matter. It's incredibly fast."

"The main reason we switched to Cerbos was to have a sophisticated authorization software to help organize and handle our authorization. We wanted to focus on domain related features and spend less time backtracking and fixing issues with our authorization."

"We got the foundation set. Now we can scale and include more complex policies. And we can grow in the right direction and with the right security thanks to Cerbos authorization management."

"Having the separation of the permissions from the code base just makes the code base more elegant. It makes the permissioning more elegant. It means they're centralized, so they're not tied to specific endpoints. And ultimately it means that different business owners have the ability to actually make updates."

"We're not worried about scaling because we can easily increase our load on Cerbos. It will also be easy for us to change how we're distributing policies as we reach different points of scale."
