Graylog Raises $39 Million in Funding

Graylog has secured $39 million in funding to help continue its significant growth momentum.

New investor Silver Lake Waterman and existing investors Piper Sandler Merchant Banking and Harbert Growth Partners led the funding.

“The growth we are seeing globally is a response to our team’s focus on innovation, a superior user experience, low total cost of ownership, and strong execution from our Go-To-Market and Customer Success teams,” said Andy Grolnick, CEO of Graylog. “We expect this momentum to continue as Graylog expands its reach and raises its profile in the security market.”

“Graylog’s solid growth underscores the strength of the extensible Threat Detection & Incident Response platform the team has built to help customers detect and respond to cybersecurity threats and leverage advanced log management for operational effectiveness,” said Shawn O’Neill, Managing Director and Group Head of Silver Lake Waterman. “We look forward to partnering with Graylog to help enable their continued success.”

Recent market expansion initiatives are also expected to help fuel future growth:

- In July 2023, Graylog entered the API Security market segment by acquiring Resurface.io’s API security platform. Graylog API Security helps customers monitor and defend the increasingly vulnerable API attack surface.

- Graylog has grown its presence in Europe and Asia Pacific by adding personnel and strategic channel partners over the past year.

- To help streamline procurement for customers worldwide, Graylog is now available on the AWS Marketplace with plans for more listings in 2024.

“Graylog’s product-led growth model, combined with its focus on customer success, continues to be an attractive combination that bodes well for its future. We’re also excited about Graylog’s expansion into the API Security space to help its customers defend this vulnerable attack surface,” said Bob Rinek, Managing Director with Piper Sandler Merchant Banking.

The company plans to leverage the new funding to accelerate product development and differentiation, scale global go-to-market operations, and bridge to profitability.
