CAMBRIDGE, MA, Threat Stack, the provider of security solutions purpose-built for the Cloud, has raised an additional $5M in funding from Atlas Venture and .406 Ventures. The additional funding will be used to further develop and commercialize Threat Stack's cloud security monitoring service, which officially launched last month, and expand its footprint with customers using Amazon Web Services.

Threat Stack's Software-as-a-Service (SaaS) provides continuous security monitoring on application workloads, helping companies detect malicious activity and protect their systems from intrusions and data loss. Optimized for the cloud, Threat Stack uses a lightweight agent on the host to enable fast deployment, auto-scaling and flexibility in elastic environments. After a highly successful and over- subscribed beta program, Threat Stack launched on-stage in November at Amazon CTO Dr. Werner Vogel's Start-up Launch keynote during the AWS re:Invent Conference.

'To address privacy and security challenges in the cloud, there exists a shared responsibility between customers and their Cloud Service Providers (CSP). Threat Stack provides a security solution that complements the CSPs existing set of security controls, and gives the customer a comprehensive security architecture for all of their cloud resources,' said Doug Cahill, CEO of Threat Stack. 'Our investors share our vision and excitement for the way we're addressing security challenges in the cloud. This latest round of funding demonstrates the support and confidence they have in the Threat Stack team as we make our move to expand and grab market share.'

The problem Threat Stack addresses is the visibility gap that exists in cloud environments. Since customers don't have access to the physical infrastructure and can't deploy traditional intrusion detection systems or other network-based security controls, they are left without the visibility they need to protect their customers and data. As a result, cloud-resident workloads and the data they access are vulnerable to malicious threats putting them at risk of intrusions and compromise.

'It's no longer a question of if you are being hacked, but if you know that you are being hacked. Threat Stack brings an invaluable service to enterprises leveraging cloud-based infrastructure, particularly those running mission-critical applications,' said Chris Lynch, partner at Atlas Venture.

'As Cloud services are increasing, so are data breaches in the Cloud. It's not enough to rely on your CSP's security solution. With Threat Stack, customers can take more control of their applications and data security through the early detection of malicious activity,' said Maria Cirino, managing director at .406 Ventures.

Threat Stack currently offers a 14-day, free trial of its Software-as-a-Service. Interested parties can signup on the company's website: https://www.threatstack.com/signup.html.
