Case Study: Perion Network Delivers Continuous Security Assurance Across a Global Digital Advertising Platform

Industry: Digital Advertising and Marketing Technology

Organization: Perion Network

Security Leadership: Ben Hachmon - CISO

Product: Terra Security Continuous Pentesting

Background

Perion Network is a global digital advertising company that helps brands connect with consumers through advanced search, display, video, and CTV advertising solutions. Operating at massive scale, Perion processes vast volumes of user data and delivers real-time advertising decisions across a highly distributed cloud infrastructure.

With a business model dependent on performance, trust, and uptime, Perion’s platforms must remain secure while continuously evolving to meet market demands and advertiser expectations.

Security Leadership in a Data-Driven, High-Scale Environment

Perion’s security leadership is responsible for protecting a complex, cloud-native environment that spans multiple products, regions, and integrations with partners and publishers.

Security must support rapid experimentation and frequent releases, while maintaining strong guarantees around data protection, platform integrity, and customer trust. This requires security controls that operate at the same velocity as engineering teams and provide actionable, high-confidence signals.

As Ben Hachmon, Chief Information Security Officer at Perion Network, explains, "Terra delivered critical insights that other pentesters missed, and they did it with correct business context and real-world material impact. This wouldn't have been possible without their advanced Agentic AI system - the next evolutionary step of cyber security."

The Challenge: Continuous Change, Continuous Risk

Perion’s engineering teams deploy frequently across a large and dynamic attack surface. Traditional penetration testing approaches struggled to keep pace with this rate of change, often identifying issues too late in the development lifecycle.

Security leadership needed a way to continuously validate exploitable risk, not just identify theoretical vulnerabilities, without slowing down teams or overwhelming them with noise.

Continuous Pentesting Embedded into Cloud Operations

By adopting Terra Security’s continuous pentesting platform, Perion embedded real-world attack simulation directly into its cloud-native development workflow.

Rather than relying on periodic assessments, Perion receives ongoing, exploit-driven security feedback that reflects the current state of production and pre-production environments. This enables the security team to surface the vulnerabilities that matter most, when they matter most.

Engineering teams benefit from early, contextual findings that are easier to remediate and aligned with how systems actually behave in production.

Focusing on Exploitability, Not Volume

Perion’s security program prioritizes validated risk over raw vulnerability counts.

Continuous pentesting allows the team to distinguish between theoretical weaknesses and issues that can actually be exploited in their environment. This reduces alert fatigue, sharpens remediation priorities, and improves collaboration between security and engineering.

Assurance for Customers and Partners

As a trusted player in the digital advertising ecosystem, Perion must demonstrate strong security posture to advertisers, partners, and cloud providers.

With continuous pentesting, Perion can show that security assurance is not a one-time event, but an ongoing capability aligned with its operational reality and cloud infrastructure.

Takeaway

Perion Network demonstrates how large-scale, cloud-native advertising platforms can maintain strong security assurance without sacrificing speed. By treating penetration testing as a continuous capability, Perion aligns security with the pace and complexity of modern digital advertising.
