We Men Can, But Women Can!

In most industries with gender disparities, it's no surprise that cybersecurity is one of them. Males have always dominated the profession, and they continue to do so now.

According to recent statistics, only 24% of the global cybersecurity workforce comprises women.

Despite these numbers, many women have worked hard in recent years to break the glass ceiling in cybersecurity and move the gender needle closer to equal representation.

Meet Katie Moussouris, the woman who beat all the odds to become the creator and CEO of Luta Security. This company enhances vulnerability coordination on overall security.

Katie Moussouris’ Early Life

Katie’s Family

Katie grew up in Boston, Massachusetts then lived in San Francisco. Her mother, Anuncia Donecia Songsong Manglona, was a single mother from the Mariana island of Luta.  

Katie identifies herself with the Chamorro indigenous people of Mariana Island. She grew up seeing the Chamorros firmly base their culture and norms on inheritance and knowing their origin.

She got bored and requested her mum to buy her another game. Because there was not enough money to buy another one, her mum gave her the manual, a programming book.

Katie started copying some programs from the book, learned about syntax errors, and discovered that punctuation was critical in programming. She already knew a lot of the basics of computer programming before getting to high school. She was the first girl in her school to take AP Computer Science.

Katie Moussouris’ Education

Katie went to study for an undergraduate course at Simmons College. Simmons University was great at its progressive educational philosophy. It is one of only a few private colleges that did not impose admission quotas on Jewish students during the 1900s.

Despite her passion for computer science, she enrolled in a molecular biology and mathematics course. She worked part-time in an MIT Whitehead Institute Lab for the Human Genome Project while studying.

The Human Genome Initiative was an international scientific research project that aimed to discover the base pairs that make up human DNA and identify, map, and sequence all the human genome’s genes, both physically and functionally. It is still the most significant collaborative biological effort in the world.

Moussouris’ Career at Microsoft

If there is something in common with Moussouris and Jonathan Siddharth is that his company was acquired by Microsoft and Katie Moussouris had an early career with Microsoft. Katie Moussouris left Symantec in May 2007 to work for Microsoft. 

She was the Senior Security Strategist Lead at Microsoft from September 2010 to May 2014. During that time, she led the Security Community Outreach and Strategy team as part of the Microsoft Security Response Center (MSRC) team.

Katie Moussouris filed a discrimination class-action complaint against Microsoft

Katie had the privilege of attending BlackHat 2008 in London, an event that brought together great minds in the cybersecurity field to talk about the future of the security landscape.

During this event, she announced the Microsoft Vulnerability Research (MSVR) program, which she came up with. This program aimed to analyze software vulnerabilities, exploit methods, track new vectors, and discover novel techniques and approaches to software security. 

Also, at Microsoft, she came up with the Microsoft BlueHat Prize incentive to motivate the community to collaborate with researchers in the security industry.

The ultimate prize of $200,000 was the greatest cash reward provided by a software manufacturer. 

During her time at Microsoft, she also established the company’s first bug bounty program, which paid out over $253,000 and discovered 18 vulnerabilities.

What’s a Bug Bounty Program?

A bug bounty program is a sponsored, organized effort that compensates security researchers for discovering and reporting previously unknown network and software security vulnerabilities. The bug bounty allows digitally connected businesses to manage and reduce their cybersecurity risks. 

Microsoft Lawsuit

In 2015, Katie filed a discrimination class-action complaint against Microsoft in federal court in Seattle after leaving the company a year before.

Katie claimed that Microsoft’s hiring policies perpetuated sex discrimination against women in technical and engineering professions. It was not only in terms of compensation but also promotions and other employment circumstances.

Although she had recognition, she felt that the women that she left behind would continue to suffer. She wanted Microsoft to change its attitude toward women, and many women admired her boldness.

Katie attributes the case’s denial of Class Action status to the legislative climate’s unfriendly toward many individuals, not just women and underrepresented minorities.


Katie Moussouris was appointed Chief Policy Officer of HackerOne, in May 2014. Hackers and security leaders passionate about making the Internet safer founded the HackerOne, a vulnerability disclosure company.

Moussouris was in charge of the company’s vulnerability disclosure strategy and promoting and legitimizing security research among organizations, legislators, and policymakers.

Hack the…Series

While still at Microsoft, Katie began negotiating a bug bounty program with the federal government. She maintained these discussions when she joined HackerOne.

Many websites, organizations, and software companies provide bug bounty programs in which individuals can gain recognition and compensation for reporting bugs, particularly security exploits and vulnerabilities.

These systems help developers find and fix bugs before they are discovered by the broader public, preventing widespread exploitation. Mozilla, Facebook, Yahoo!, Google, Reddit Square, Microsoft, and the Internet bug bounty are just a few companies that introduced bug bounty programs.

Companies are now using bug bounty programs outside of the technology industry, including typically conservative entities like the US Department of Defense.

Hack the Pentagon

The Hack the Pentagon pilot, the United States Government’s first-ever bug bounty, began on April 18, 2016, and ended on May 12, 2016

Being the chief policy officer at HackerOne, Katie assisted the Defense Department in launching the Hack-the-Pentagon initiative. The initiative came as the first federal bug bounty program that promises to compensate hackers who find vulnerabilities in the Department of Defense’s public-facing website.

It gave hackers legal permission to perform specific hacking techniques against Department of Defense (DoD) websites, with financial rewards for successfully submitting vulnerability reports. The pilot produced impressive results that far exceeded expectations.

The Pentagon uses bug bounty programs as part of a shift in policy that has seen various US government agencies shift from threatening white hat hackers with legal action to inviting them to engage as part of a whole vulnerability disclosure framework or policy.

The program’s goal was to encourage the next generation of hackers to come forward and assist the government without fear of legal repercussions or incarceration.

An example is Dworken, an 18-year-old boy who hacked the Pentagon during the Hack the Pentagon initiative. He was one of 1,400 people chosen to participate in the Hack the Pentagon beta program.

During the 24-day pilot of Hack the Pentagon, they fixed 138 vulnerabilities bug bounty challenges for DoD assets, demonstrating its efficacy.

Hack the Airforce

Hack the Air Force was Katie Moussouris’ response to the Pentagon’s effort

Hack the Air Force was Moussouris’ response to the Pentagon’s effort. On October 20, 2016, the Department of Defense announced a three-year deal with HackerOne to spread these initiatives to other agencies. 

Secretary of the Army Eric Fanning spearheaded the first of these programs- Hack the Army -which remains the most ambitious Government Bug Bounty Program.

Shortly after the launch of Hack the Army, the US Department of Defense (DoD) published the Vulnerability Disclosure Policy (VDP) on HackerOne, laying out a legal path for any hacker to submit vulnerabilities in any DoD public-facing systems. This policy is a first for the United States government.

Currently, Katie is a member of the Cyber Safety Review Board, the Information Security and Privacy Advisory Board, and the Information Systems Technical Advisory Committee for the United States government. She advises the government on the benefits of security research and hacking to keep the internet safe.

Katie Moussouris’ Recognitions

Wassenaar Arrangement Amendment

Ms. Moussouris is one of two private industry official US technical experts working with a group of representatives to renegotiate the Wassenaar Arrangement. She effectively clarified exemptions for vulnerability disclosure and incident response in export restrictions.

The Wassenaar Arrangement is a 41-nation export control framework that encourages transparency in national export control regimes for conventional weapons and dual-use commodities and technologies.

Katie Moussouris and the Wassenaar Arrangement

It was designed to protect citizens from human rights violations. However, the legislation got revised in 2013 to cover intrusion software which had the potential to devastate the cyber security community.

She wrote an open letter to Wired magazine criticizing the move as harmful to the vulnerability disclosure industry because of the overly broad definition. She invited fellow security experts to submit comments to help regulators understand how to implement the changes. 

Because of this, she got an invitation as a technical expert to assist in the Wassenaar Arrangement negotiations in the United States. She helped rewrite the amendment to adopt end-use decontrol exemptions based on the user's intent.

Women in IT Security List

The SC Magazine named Moussouris to its Women in IT Security list. The SC Media Women in IT Security program honors leaders who have faced security challenges and positively affected the advancement of cybersecurity in government or the private sector.
