Mobile apps have become a primary interface for critical services, including banking, payments, and

healthcare. Unlike web applications, much of the logic and intellectual property in a mobile app

lives directly on the user's device, which is an environment the developer doesn't control.

That makes mobile apps uniquely exposed to reverse engineering, runtime manipulation,

and fraud. As more critical functionality shifts to mobile, the need to harden apps against sophisticated

attackers continues to grow. Guard Square builds tools to protect and test mobile applications

against both static and dynamic threats.

Its platform has features including layered code obfuscation, runtime application self-protection,

mobile specific security testing, threat monitoring, and API attestation.

Ryan Lloyd is the chief product officer at Guard Square.

In this episode, he joins Gregorvan to discuss why mobile security differs from desktop and web security,

how reverse engineering tools have evolved, the role of compiler-based obfuscation and runtime protections,

common mobile app vulnerabilities, and how LLMs are reshaping the attacker

landscape. Gregor Vand is a security-focused technologist, having previously been a CTO across

cybersecurity, cyber insurance, and general software engineering companies. He is based in Singapore,

and can be found via his profile at

van.hk or on LinkedIn. Hello and welcome to Software Engineering Daily. My guest today is Ryan Lloyd. Hi there. Great to be here.

Yeah, great to have you here, Ryan. So you're the chief product officer of Guard Square. We're going to be hearing all about

Guard Square through the episode and everything, mobile app security,

not a topic that we've covered in much depth before. So this is going to be an interesting one.

But as we like to do on SE Daily, just what was your path to Gards Square, I guess, and I'm becoming

the CPO at Garn Square? Yeah. So for 20, 25 years now, I've been working for a series of companies that provide
