Andersen Consulting has expanded its footprint with the addition of three Spain-headquartered collaborating firms, strengthening its capabilities in cybersecurity and life sciences.
The joining of forces with A3Sec grows Andersen Consulting’s expertise in cybersecurity, including threat detection, incident response, and exposure management.
Headquartered in Spain, with further offices in Mexico, Colombia and Ecuador, A3Sec has a team of more than 180 cybersecurity professionals. The firm delivers integrated cybersecurity services, including managed detection and response, cyber telemetry, threat intelligence, and crisis management to clients in sectors such as financial services, telecommunications, energy, and government.
“Our purpose has always been to protect the digital environment through innovation and accountability,” said Javier López-Tello, CEO and founder of A3Sec. “Through Andersen Consulting’s global platform and resources, we can now deliver end-to-end professional services to our clients seamlessly.”
The addition of Ambit Iberia bolsters Andersen Consulting’s expertise in digital and regulatory solutions for the life sciences sector.
