Most of our work is the project that kept slipping: an identity platform going out of support, an ERP that has to reach the cloud, a data warehouse nobody wants to touch, an AI pilot with no route to production. We bring certified engineers for 58 platforms and stay until your team can run the result.
Big programs rarely stay in one lane. Moving to the cloud drags identity in with it. An ERP upgrade turns into a data project, and AI ends up touching most of it anyway. With the practices in one firm you get one plan, where you'd otherwise be juggling four vendors.
Identity governance, privileged access, Entra and Okta, customer identity, OT security, and the service accounts and AI agents nobody owns.
Salesforce, Dynamics 365, ServiceNow, Workday, SAP, Oracle, Guidewire and Epic. We build on them, upgrade them and move them to the cloud.
We move warehouses and lakehouses to Snowflake, Databricks and Fabric. Then we build the pipelines and models and put governed access around them.
Forward deployed engineers, agents and MCP servers. Evaluation and AI security. And the adoption work that turns licences into people actually working differently.
We run data center exits and VMware moves, build landing zones, and work in Kubernetes and OpenShift. The infrastructure is written as code.
Web and mobile apps, APIs and integration work. On the mainframe side, we modernize in slices small enough to test.
We handle device identity and edge gateways, and pull industrial data out of PI historians. Vendor access into the plant gets recorded.
Certified engineers for platforms that are hard to hire for. Onsite, nearshore or offshore, either as a team of ours or inside yours.
Pick one. You'll see what we'd do first and the case studies closest to it. All 66 case studies are in the library.
IdentityIQ 8.x, CyberArk LTS versions, Windows Server 2016, Auth0 Rules, .NET 8, SAP ECC. Every estate has a handful of these, and each one hides custom code nobody wants to touch.
We count what's custom, rehearse the upgrade on a copy of production and plan the window against the vendor calendar.
The easy workloads moved first. What's left has hard dependencies, old licences and a VMware renewal that got more expensive.
We do the rest of the move in waves. The landing zones, identity and networking for each wave get built as code first, and only then does that wave start.
There's a demo for every proof of concept. Nobody owns it, there's no evaluation set, and it can't reach the systems where the work actually gets done.
Forward deployed engineers sit with one business team and ship a scoped agent into a real workflow, with evals and access controls.
Two identity providers. Two CRMs, two ERPs. The people on both sides have to start working together next week, and somebody still has to pick which platform you keep long term.
We get people working on day one with federation and cross-tenant sync. Consolidating onto one platform comes later, on a plan.
Access reviews in spreadsheets, privileged accounts nobody rotated, service accounts with no owner, and evidence assembled by hand every quarter.
Controls that produce their own evidence: owners on every account, rotation on every secret and reviews that close properly.
Guidewire, Murex, CC&B, IS-U, RACF or Epic experts are scarce. Agency candidates have read about the platform but never run it.
We put certified engineers in front of our own practitioners and have them work on the real platform before we send them. Onsite, nearshore or offshore.
COBOL and CICS, Oracle EBS customizations or an AX 2012 instance sit under the roadmap. A full rewrite is unrealistic, and leaving it alone has stopped being an option.
We write down the parts that matter and put APIs in front of them. The rest moves over in slices small enough for the business to test.
Planned for or not, somebody has to decide what these assistants can read, what they can change, and who's reviewing them. Better before the release than after.
Permissions and data boundaries come first, before anyone gets a login. Then a pilot group. We watch what they do with it, and widen the rollout when it holds.
Every platform page talks about the vendor's own AI, and about where agents and MCP servers fit. We do the actual building in the four services below.
Engineers who sit with one business team and ship working AI into the tools those people already use.
Agents reach SAP, Salesforce, ServiceNow and internal APIs, but only by way of MCP servers that we scope and log.
Eval sets. Regression tests for prompts and models. Cost tracking. Rollouts that don't break things.
We test for prompt injection, see what tools are permitted to do and look for data leakage. Controls get mapped to NIST AI RMF and ISO/IEC 42001.
The client's name is left out of each one. What's in is the problem, the before-and-after architecture, the plan phase by phase and what changed. Pick an area, or start with the one below.
Start with an assessment, so you know what's actually there. Then the engineers who did it can build the thing, and stay on to run it or join your team if you want.
Count what's really there before anyone signs a large statement of work.
A fixed scope, delivered by the engineers who scoped it.
We run the platform with your team, or add certified engineers to it.
The engineers who ran a project write down what they learned. Ten minutes, tops. A diagram up front, jargon explained as you go, three questions at the end. Here's one to try.
A tier-1 support rep invokes an agent. Someone asks it to issue a large refund the rep couldn't issue by hand. What should happen?
Cohash is an engineering firm for enterprise migrations, upgrades, cloud moves, AI and security. We work across 58 platforms, from SailPoint, Entra ID and CyberArk to Salesforce, ServiceNow, Workday, SAP, Guidewire, Epic, Snowflake and Databricks, and we staff certified engineers for them.
Frisco, Texas is headquarters. From there our engineers work onsite in the US, and we also staff nearshore and offshore, which covers us across time zones.
We work with it. In most engagements your engineers and ours pair up. At the end we leave runbooks and hold handover sessions, and your team runs it from there.
Yes. Send us the platform, your version and your date. We read the vendor's notes against your path and tell you what we'd do first.
