Cisco said it plans to purchase UK-based cybersecurity consultancy Portcullis.
Portcullis focuses on enterprise and government sector clients in Europe.
Cisco said the acquisition will help accelerate its own security services business. Terms of the agreement were not disclosed.
Cisco said the purchase complements last year's purchase of Neohapsis, a security consulting firm that evaluates corporate security, risk and compliance.
"Together, Cisco and Portcullis will provide strategic guidance to our clients to help them with their most difficult security challenges," said Rob Salvagno, VP Corporate Business Development at Cisco. "Through this acquisition, we increase our ability to offer robust security, risk and compliance services to help clients overcome operational and technical security challenges, anticipate and respond to new threats, and drive new business."
Portcullis' services include assessments to identify vulnerabilities, forensic testing, first responder training to prepare for attacks, policy review and creation, security awareness training, and overall security posture audits.
The acquisition is expected to close in the second quarter of Cisco's fiscal year 2016.
