Adam Dimopoulos joins as Chief Information Security Officer

Entrust has appointed Adam Dimopoulos as Chief Information Security Officer, adding a senior security executive with more than 20 years of experience to its leadership team.

Dimopoulos joins the identity and security software provider from Synchrony, where he served as Vice President of Information Security and led identity security and Zero Trust initiatives across the business. He will be responsible for strengthening Entrust's security posture and resilience as it works to protect customer systems and data.

He brings experience in security, identity and risk management to the centre of Entrust's internal security strategy. The role covers the protection of critical systems and data while supporting product development and broader business operations.

Before Synchrony, Dimopoulos held leadership and advisory roles at Microsoft and Gartner. Those positions gave him exposure to both product development and customer-side security challenges, a combination Entrust is emphasising as it expands its focus on identity-related security.

The appointment comes as security vendors face growing scrutiny over both their internal controls and the products they sell. Large corporate and public sector customers increasingly expect software and infrastructure providers to demonstrate strong governance, resilience and risk management, particularly when they handle identity, authentication and other sensitive services.

Entrust operates in digital identity, certificate management, cryptographic security and fraud prevention. Its products are used by organisations that manage access to systems, verify users and secure transactions, making the Chief Information Security Officer role highly visible to customers as well as internal teams.

Anudeep Parhar, Entrust's Chief Operating Officer, framed the hire around trust and risk management.

"Customer trust is at the core of everything we do," Parhar said. "Adam's proven leadership in identity security and risk management will help ensure our customers can rely on Entrust to protect their most critical systems and data, even as their security needs grow more complex."

For Entrust, the appointment also reflects the rising profile of identity security as a management issue rather than a narrow technical function. Companies across regulated industries are placing greater emphasis on controls around who can access systems, how that access is verified and how security teams limit the impact of breaches when they occur.

Zero Trust, one of the areas highlighted in Dimopoulos's background, has become a common framework for those efforts. The approach centres on continuous verification of users and devices rather than assuming trust based on network location or previous access. Financial services groups and other regulated organisations have been among the most active adopters because of the sensitivity of customer records and transaction systems.

According to Entrust, Dimopoulos's work at Synchrony involved enterprise-wide identity security and Zero Trust transformation. That experience is expected to help the company improve resilience and maintain confidence among customers that depend on its services for critical operations.

His own comments suggested that combination of vendor and buyer experience was a key reason for the move.

"I've had the opportunity to see identity security from both sides-helping build products and platforms, as well as being accountable for the outcomes as a global security leader," Dimopoulos said. "That 'builder-and-buyer' perspective helps ground security in what actually works at scale. I'm excited to continue advancing the conversation on modern identity and Zero Trust-with outcomes that are measurable, resilient, and practical for real-world environments."

Entrust supports customers in more than 150 countries through a global partner network. That international reach means its security leadership must address a wide range of operational, regulatory and customer requirements across markets, particularly in sectors such as finance, government and large enterprises, where identity controls and data protection are closely monitored.

In this part of the cyber security market, senior appointments often serve a dual purpose: shaping the internal security agenda while signalling to customers that the supplier is investing in governance and oversight at a time when buyers are asking harder questions about resilience, access management and the security of third-party providers.
