We encourage you to apply even if your experience is not a 100% match with the position.

About Us
We didn’t start out as a traditional security product. In the beginning, Glasswall was one of only two file sanitisation filters in the US Intelligence Community’s highly classified networks. We are rated #1 by the National Security Agency. We designed Glasswall CDR to protect businesses against the most advanced file-based threats. Today, we’re trusted by commercial and government organisations around the world.
In June 2025 Glasswall officially entered a new era of growth and innovation having been acquired by the leading private equity firm, PSG Equity. This marks a significant milestone for our company—one that underscores the strength of our business, the dedication of our team, and the exciting potential that lies ahead.
With PSG’s strong track record of scaling high-growth cybersecurity and technology businesses, we are better positioned than ever to accelerate innovation, expand into new markets, and deliver even greater value to our clients, employees, and stakeholders.
Cybersecurity is a mission-critical field, and we’ve always believed that staying ahead means moving faster, continually adapting to meet new challenges and investing more boldly in the future. This partnership empowers us to do exactly that—while maintaining the same leadership, values, and commitment to excellence that have brought us this far
We’re excited for what’s to come—so now is a great time for you to join us on our journey.
Inclusion
At Glasswall we believe that diversity of people and thought are central to our purpose. We are committed to making Glasswall a company that is attractive to people of many different backgrounds. This includes diversity in every sense of the word: those with different backgrounds, ages, ethnicities, gender identities, sexual orientations, ways of thinking and those with disabilities or neurodivergent conditions. We therefore welcome and encourage applications from everyone, including those from groups that are under-represented in our workforce.
One of our corporate objectives is to ensure that the organisational health of the firm is highly rated by our employees. We believe that this is only possible if we promote a culture of inclusion and respect across our business. Every six months we survey employees on a range of questions relating to our organisational health. This holds a mirror-up to a business and ensures that we can focus on where we need to do better.
We have an Organisational Health Committee, which is chaired by a non-executive position. The panel has been formed to guide the leadership in taking positive action that supports a good work-life balance, family friendly relations and to be inviting to a diverse range of potential employees.
We also have a Women in Technology Group which has been formed to promote balance in the way that we communicate with, promote, encourage, and support people across our business.
Work/Life Balance:
Our team puts a high value on work-live balance. It isn’t about how many hours you spend at home or at work; it’s about the flow you establish that brings energy to both parts of your life. We believe striking the right balance between your personal and professional life is critical to life-long happiness and fulfilment. We offer flexibility in working hours and encourage you to find your own balance between your work and personal lives.
Salary and Benefits:
* Glasswall offers a competitive salary.
* Performance related bonus scheme.
* We offer flexible and remote working options, with hybrid working from our Central London office.
* Office travel and incidental WFH expense coverage.
* 25 days holiday (plus public holidays).
* Private Medical Insurance including mental health support and cancer care.
* Enhanced sick pay.
* Annual investment in training and professional development.
* Company sponsored life, critical illness, and income protection insurance.
* Contributory pension scheme.
* Access to ‘salary sacrifice’ benefits such as Cycle to Work and Tech Schemes.
A successful candidate will live in the United Kingdom and is comfortable working from home with some meetings being held in the London office.
