Prosimo
Prosimo provides a multicloud networking and security platform that combines application-aware connectivity, security controls, and cloud cost management for enterprises running workloads across multiple public clouds.

Prosimo was founded in 2019 by a team with roots at SD-WAN pioneer Viptela, applying similar principles — application-aware traffic engineering and centralized policy — to multicloud network security. The platform is built to give enterprises consistent connectivity, security controls, and observability across AWS, Azure, and GCP from a single control plane, while also surfacing cloud networking cost data that is often opaque to security and network teams.
Bundling cost visibility alongside security and connectivity is a notable differentiator: cloud egress and data-transfer costs are a real, recurring pain point for enterprises, and Prosimo positions its platform as helping teams optimize spend at the same time they enforce policy. The company has raised roughly $55M from investors including General Catalyst, BlackRock, and Redline Capital.
For CISOs, Prosimo is most relevant to organizations already committed to a serious multicloud strategy who want a single place to enforce consistent network security policy without duplicating effort across each cloud’s native tools.
Innovation Matrix Assessment
Prosimo has steadily added security and observability features to its original application-experience platform, though at a measured pace typical of a Series B-stage company.
Pairing security policy enforcement with cloud cost visibility gives security and network teams a practical, budget-relevant reason to consolidate tooling.
At roughly $55M raised, Prosimo trails better-capitalized direct competitors like Aviatrix and Alkira, suggesting comparatively modest momentum in a crowded category.
Its combined security-plus-cost-optimization angle is a meaningful product differentiation, but the underlying multicloud networking architecture is similar to several well-funded peers.
Enterprise deployments are referenced in company materials, but independent, vendor-neutral efficacy or performance benchmarking was not found.
Multicloud complexity and rising cloud networking costs are both durable enterprise pain points that keep this category strategically relevant.
Why CISOs Should Care
Prosimo gives security teams one place to enforce consistent network access and security policy across multiple public clouds, avoiding the drift that comes from separately managing each cloud provider's native networking and security constructs.
What Makes It Different
Combining cloud networking cost optimization with security policy enforcement in the same platform is an unusual pairing that most competitors treat as entirely separate problems, giving Prosimo a cross-functional pitch to both network/security and finance stakeholders.
The Matrix Verdict
52/100 — INCREMENTAL INNOVATOR
A technically capable multicloud networking and security platform from an experienced founding team, competing in a crowded field (alongside Aviatrix and Alkira) where differentiation increasingly comes down to execution and enterprise reference accounts rather than architecture alone.
