* October 8, 2021 Update: Pleased to announce we have completed the acquisition of Epsagon! Welcome Epsagon team to Cisco!

I’m pleased to announce our intent to acquire Epsagon Ltd., a privately held, modern observability company with offices in New York and Tel Aviv. Named by Gartner as a “Cool Vendor in Performance Analysis with expertise in distributed tracing solutions for modern applications and technologies, including containers and serverless environments, Epsagon will play a key role in expanding and accelerating Cisco’s comprehensive Full-Stack Observability roadmap.

Applications have become part of our everyday life and are the primary way we interact with products and services today. Increasing consumer demand for a seamless digital experience with each application interaction – whether shopping for groceries, ordering meals, buying a car, applying for a loan or getting work done – means businesses must ensure that every component of their application – third-party or otherwise – runs smoothly.

As the application market’s competitive landscape surges, businesses must fast-track their innovation timelines. If they don’t innovate swiftly, another company will beat them to it. To accelerate application development lifecycles, businesses are adopting cloud-native technologies, microservices and containerized components on a large scale while leveraging an extensive web of traditional components, third-party services and application programming interfaces.

This has led to a significant increase in complexity in IT environments. Multiple teams are involved in figuring out how to monitor the performance, optimization and security of every digital experience, by examining each component, such as application services, networks, infrastructure, cloud and databases, and understanding the insights gathered and their impact to customers’ digital experiences. Traditional domain-centric monitoring tools address only some of these needs and for a single area at a time.

Cisco Full-Stack Observability

Cisco’s approach to full-stack observability gives our customers the ability to move beyond just monitoring to a paradigm that delivers shared context across teams and enables our customers to deliver exceptional digital experiences, optimize for cost, security and performance and maximize digital business revenue. While most vendors only focus on visibility across a technology stack, we believe that full-stack observability capabilities need to provide all teams with full-stack insights and full-stack actions that result in improved business and digital customer experiences.

Our core SaaS solutions for full-stack observability include AppDynamics, ThousandEyes and Intersight. Our Full-Stack Observability platform, comprised of these solutions, provides observability across the entire stack of applications, network infrastructure and security with real-time insights correlated across domains and integrated with business context powered by AI and machine learning. This gives all the involved teams full visibility across the stack so they can take quick actions. Teams are then able to tie performance back to core business metrics and prioritize actions based on business impact.

Cisco Full-Stack Observability helps customers solve three main challenges:

  • Performance: application performance is improved, and metrics are correlated with business outcomes to provide a flawless application and user experience. This works across hybrid and modern / cloud-native applications.
  • Optimization: Customers can dynamically match infrastructure needs and costs to application and business demands.
  • Security: Teams can actively identify and block vulnerabilities in production runtime and secure the application development process, creating shared context between application and security teams.

Epsagon’s technology and talent align well with Cisco’s vision to enable enterprises to deliver unmatched application experiences through industry-leading solutions with deep business context. By contextualizing and correlating visibility and insights across the full stack, teams can improve collaboration to better understand their systems, solve issues quickly, optimize and secure application experiences and delight their customers.

When the acquisition closes, the Epsagon team will join our Strategy, Incubation and Applications group.
