Managed Technology Services for ISVs

Scale your software business without scaling your IT overhead

Accelerate your roadmap. We'll manage the platform. Independent Software Vendors (ISVs) building and scaling SaaS products need infrastructure that keeps pace with growth - without pulling developers off the roadmap to manage it. We provide the managed Kubernetes, CI/CD, and CREST-certified security to help you scale faster and more securely.

41%of organisations lack high confidence in their open-source security.

Application platform migration and management

Your product has outgrown the way it is hosted. Perhaps it began on a SQL Server under a desk, a private platform that no longer scales, or an AWS landing zone set up quickly when the business was smaller.

Claranet assesses the application and the platform together. We determine what should stay, what should move and what is worth modernising, then help you choose AWS, Azure, private cloud or hybrid on the merits rather than on habit.

  • Assess before you move: Application fitness, dependencies, performance, security and cost reviewed before a migration path is agreed.
  • Modernise where it pays: Refactor databases, containerise workloads, improve CI/CD and remove infrastructure bottlenecks where there is a clear return.
  • Use funding where eligible: We help identify programmes such as AWS MAP and Microsoft Azure Accelerate that can offset assessment, migration or modernisation costs.
  • Run it after the migration: Managed cloud, observability, SRE, FinOps and 24/7 operations keep the platform reliable while your team builds product.

Built for software companies making the shift to SaaS

Financial Software Limited had spent over 16 years serving UK financial institutions - then moved to a SaaS model to meet changing customer expectations. Scaling that shift meant they needed an IT environment as flexible and reliable as the service they were promising customers. We designed and built the fully managed solution behind it.

ISV Platform FAQs

  • An ISV (Independent Software Vendor) is a company that builds and sells software products - often as SaaS - rather than developing software for internal use only. We support ISVs by managing the underlying platform: Kubernetes, CI/CD pipelines, security, and cloud cost, so your team can focus on the product instead of the infrastructure it runs on.

  • We manage your Kubernetes environment (EKS, AKS, or GKE), automate and integrate your CI/CD pipelines, and provide full-stack observability and performance tuning. Alongside that, we offer CREST-certified penetration testing and 24/7 Managed Detection & Response, so your platform is monitored and secured as well as run.

  • Cloud spend is wasted on average 28% of the time - usually through over-provisioned resources that aren't scaled to actual demand. Our FinOps and cost optimisation service analyses your usage patterns and implements right-sizing and auto-scaling, so you only pay for the infrastructure your application actually needs.

  • Yes - our penetration testing is delivered to CREST OVS (OWASP Verification Standard) accreditation, which is specifically designed for application and mobile app security testing rather than general network testing. That makes it directly relevant to SaaS products, where the application layer is usually the biggest attack surface.

  • Yes. We provide expert support across both legacy and modern data platforms - including Oracle, MS-SQL, and Informix, as well as Databricks and Snowflake — so you don't need a separate partner for your data layer alongside your infrastructure.

  • No. Our managed Kubernetes service covers EKS, AKS, and GKE, so we work with you on AWS, Azure, or Google Cloud - whichever platform your product already runs on, or whichever you're planning to move to.
