Billions of people around the world use Meta technologies to connect with their friends, families and communities. Our Security team helps make sure our platforms offer safe environments for people to message loved ones, build businesses, raise funds for causes they believe in and more. Supporting our global community is a tremendous responsibility that requires continuous improvement of and investment in our tools and talent. People who work on our Security team use the latest technology and collaborate with others across our world-class team to solve problems of unprecedented scale.

At Meta, we take what’s called a “defense-in-depth” approach to security. This means we layer a number of protections to make sure we prevent and address vulnerabilities in our code from multiple angles. The Security team responds to security issues and proactively looks for opportunities and new ways to strengthen our defenses so we can counter emerging threats and stay ahead of our adversaries.

From building the coding frameworks to help engineers build secure code to developing automated detection tools to help spot bugs at scale to running one of the oldest bug bounty programs in the industry to working alongside product teams to build security into each feature, our team is committed to finding, fixing and preventing bugs across our platform.

Our Security Engineering organization is centralized around four areas: prevention; detection and response; measurement and validation; and program and operations. Our prevention pillar proactively reduces a potential attacker’s ability to compromise our data or systems. Our detection and response pillar is focused on identifying and responding to threats. The measurement and validation pillar independently evaluates our prevention, detection and response efforts to ensure they are in line with our risk, and avoid regression. Lastly, our program and operations pillar streamlines communication, drives engagement and optimizes processes for both internal and external security initiatives.

From security engineers and data scientists to penetration testers and forensics engineers, our team comprises people with diverse backgrounds and skillsets. The Security team is dispersed across Meta's offices around the world—London, Seattle, New York, Singapore and Washington DC—to ensure we approach every challenge with a global view and can make an impact at scale and around the clock. But all our Security teams have one thing in common: we’re all working to create a safe and secure community.

The Security organization at Meta is focused on evolving and innovating our defenses to support Meta’s mission of giving people the power to build community and bringing the world closer together. Our focus on finding, fixing and preventing security issues has allowed us to continuously scale our defenses as Meta technologies have grown to support billions of people connecting with one another. And because we know that security work is never 100% finished, our Security team continues to innovate as the Meta community grows.

Guy Rosen is Meta’s Chief Information Security Officer (CISO). As CISO, Guy oversees safety and security, combating both on-platform abuse and protecting the security of our products, infrastructure and company information. He brings over two decades of cyber security, software development and product management experience. Since 2017, Guy led an overhaul of the company’s approach to fighting abuse on the platform and built our industry-leading Integrity teams that pioneered approaches to complex challenges such as harmful content, election readiness and adversarial threats. Guy first joined Meta in 2013 following the acquisition of Onavo, where he was co-founder and CEO.

Clyde Rodriguez began his career in robotics and AI research at Stanford Research Institute International and NeXT Inc. before joining Microsoft where he spent 15 years. He led the development of Microsoft’s first commercial 64-bit Windows operating systems and formed and led the company's Azure Networking team. Clyde also served as the Chief of Staff and Technology Advisor to the CEO of semiconductor company Advanced Micro Devices. He has served as an advisor to the United Nations on the use of technology for global development, a Board Director for MIT’s One Laptop per Child project, the Director for First Place School, which serves homeless children and their families in the Seattle area, and is currently a member of UC Berkeley’s College of Engineering Advisory Board. He also helped form NYC FIRST, a nonprofit dedicated to inspiring youth through robotics and has mentored Brooklyn high school students in building robots as part of the region's FIRST robotics competition program. Clyde has a B.S. degree in Electrical Engineering and Computer Science from UC Berkeley and is a 2020 recipient of the university’s Distinguished EECS Alumni award. Clyde is also an alumnus of Harvard Business School’s Executive Education General Management Program.

“I love working on security at Meta because I can experience how it makes the world a better place first-hand. Whenever I see people on the bus using Facebook, I know I’ve stopped bugs that could cause harm. It makes me feel proud every time. I recently had the opportunity to help train a new static analysis tool that can find security bugs automatically. This helps us secure the platform faster than ever before, and it’s because of the work I’ve done. My advice to other people who want to work in security is this: be prepared to jump into the things you’re passionate about. In this industry, you really can’t do better than protecting people on Facebook.” —Rachel E., Security Partner

“One of the most interesting efforts we tackle here at Meta has been working to create and improve scalable solutions for security reviews across our family of products. In addition to our secure application frameworks and static and dynamic analysis tools that help us build secure code from the ground up, we’ve also built a self-service model that empowers software developers to spot security risks and mitigate them on their own as they design new systems and write new code.” —Sami E., Application Security Manager
