Pros

A lot of your colleagues are super clever and genuinely lovely people.

Cons

Leadership positions are occupied by individuals who, in many cases, lack the professional and life experience necessary for their roles. Decision-making is inconsistent, and employees struggle to trust leadership’s direction. The company often states that it “doesn’t follow the herd,” yet there are books strewn around the office about what other companies have done, which we then implement with a "twist" which is much more inefficient and demoralizing. The new quarterly review system is one of the most demoralizing changes introduced. It is opaque, highly political, and prioritizes visibility over actual performance. Decisions are made by individuals who should not be involved, and team leads are not allowed to explain the reasoning behind outcomes—most likely because they had little say in them. This system has already caused significant stress, with at least one person taking sick leave due to the pressure. Concerns raised about this process are ignored, and trust in management continues to decline. Senior management openly say that the performance reviews went well, even with all of this. Management frequently emphasizes emotional intelligence, yet their actions consistently demonstrate the opposite. At the start of 2024, after a difficult end to 2023, the CEO made a statement suggesting AI would replace employees. When concerns were raised, they later claimed that was not the intended message—but the fact that it was interpreted that way speaks volumes about a lack of awareness. There have been many more similar incidences. Job security is uncertain. Employees are frequently let go without clear explanations, only being told that their “goals and values are unaligned.” It is an open secret that some departing employees are pressured into signing NDAs. Leadership refers to the firing process as “the immune system,” implying that employees who do not fit are viruses. Pay reviews are infrequent, and there is no transparency in how compensation decisions are made, due to the flat non-hierarchichal hierarchy (make it make sense). Despite claiming to have a “default to open” culture, transparency is severely lacking. Teams are constantly reshuffled. Developers are moved between teams with little or no notice. Additional responsibilities are thrown on to teams that are already thinly spread with minimal thought and support, other than the fact that "we should all own the problem" i.e. management wash their hands of it and blame the employees when it goes wrong. Major decisions are made privately, and employees often learn about changes only at the last minute. The company’s own messaging states that “nothing can’t be talked about,” yet in reality, very little is openly discussed. Culture surveys are not anonymous. Employees are required to complete them, and the consistently positive results do not reflect the concerns widely shared internally. A fully independent third-party review is necessary. Leadership needs to engage directly with teams to understand the reality of working here, rather than relying on flawed internal surveys. However, when concerns are raised—whether about job security, the performance review process, or overall direction—employees are often dismissed as “misunderstanding” the situation and told they need additional “training” or “education.” This approach prevents meaningful feedback from being acknowledged or acted upon. A lot of people at PortSwigger, across business functions, long tenured or short tenured, graduates or experienced, have the same opinions and concerns, but are never listened to. Instead, everyone who does complain are told they are in an echo chamber and dismissed as above. It is also well-known internally that employees who post negative reviews about the company are sometimes pressured into removing them, and ex-employees who found that their goals and values are no longer aligned are forced into signing NDAs, so they can't publish what they think. The lack of work-from-home flexibility is severely limiting hiring efforts. The company has exhausted its talent pool in the North West and is now opening a London office, yet even that has not significantly improved recruitment. These ongoing issues are creating a workplace where employees feel undervalued, unheard, and uncertain about their future. Prospective employees should be aware of these challenges before considering a role here. Leadership needs to acknowledge and address these problems before more high-performing individuals leave.

I am sorry that you feel this way. It must be painful to feel disconnected from the culture you work in, and it’s certainly not the experience we want any Swigger to have. Of course, no individual or business is perfect. We all make mistakes. I certainly do. Our hope is always that we learn from those mistakes and treat ourselves and one another with understanding and compassion as we do so. I want to reassure you that you are heard. We work hard to gather perspectives from Swiggers through many different channels, and the feedback we receive is both rich and balanced. This makes us confident that most Swiggers feel comfortable sharing their honest views (both positive and negative) and our qualitative and quantitative data reflects that. Some of the concerns you mentioned were also highlighted in our culture survey. Others have been shared directly with me and other leaders, and we greatly appreciate the honesty. We are doing our best to support the small number of Swiggers who feel this way, always approaching them with compassion and understanding. We know that a few Swiggers have made some assumptions about our new performance review process. If you speak to us, we can help clear these up and hopefully ease any worries you might have on the issues you raised. If you have not already done so, we encourage you to discuss the feelings you described with your team leader or anyone on the Culture team. It is true that we have an unapologetically high-performing culture. Our goal is to hire the very best people, invest heavily in their development (through coaching, feedback, and other learning opportunities), and set ambitious goals for ourselves. We believe we can achieve our best work as a focused team of exceptional, “dream-team” players. Most Swiggers thrive in this culture, finding inspiration from their colleagues to aim even higher. They are proud of what we accomplish together and look forward to collaborating with people who are both highly capable and fun to work with. For this culture to work, it is vital that individuals buy in to it, in terms of both their own growth mindset and their commitment to empowering others. We are committed to rewarding Swiggers based on the value of their contribution. Many Swiggers receive rewards that far exceed normal market ranges, reflecting their outstanding impact, and we regularly review these rewards. At any given time, we are normally supporting a small number of Swiggers (well under 10%) whose performance falls significantly below our established bar. During that period, these individuals do not receive salary increases, aligning with our philosophy of rewarding people based on the value of their contribution. We recognise that our high-performing culture is not for everyone, and we do not assume our culture is “right” while others are “wrong”. Our culture is ours, and it is right for us. There is no shame in realising that you might feel more fulfilled and less anxious in a different environment. In such cases, we do everything we can to be supportive and help each individual to understand what they want and to find the opportunity that best suits them. Dafydd Stuttard - Founder & CEO

Good pay. Bad superiority complex.

Pros

Above average compensation. Good developers, and effort is put into code quality. Holidays can be taken on short notice.

Cons

There's a lot of talk about the value of emotional intelligence and humility. At the same time, there's been a problem with arrogance and an attitude within the company that people at PortSwigger are automatically superior to everyone else. Some buy into this while others are quietly disgusted. The founder is one of the least emotionally intelligent people I've met and has said things that are bafflingly tone-deaf or arrogant, and I think this is where a lot of the cultural problems stem from. I've found the "flat" structure to be superficial. Realistically, there's a clear heirarchy and opinions are weighted correspondingly. Having a heirarchy isn't a problem per se, but to claim everyone's input is valued equally would not be fair. I also find the idea of "fun" being an important factor in work to be nonsense. The work allocated depends entirely on what's important to management. Again, nothing wrong with this in principle, but the claims to the contrary bother me.

Thank you for your review. We are always keen to receive feedback, even when it is difficult to hear. I’d like to respond to some of your comments. It is true that we have exceptional people and we give due praise for their amazing work. Celebrating our success is actually something we have had to work at. Because we set such a high bar for ourselves, it is all too easy to view brilliant performance as “expected” and not give colleagues enough praise. Further, many (maybe most) of our people are in the “anxious over-achiever” mould, and are prone to doubting their own abilities. I am shocked that you have heard colleagues talking about being superior to others. In my experience it is rare to hear anyone blowing their own trumpet, let alone claiming superiority over others. There are of course many other incredible people working elsewhere. We’d love to hire more of them. Regarding my own emotional intelligence, like many people I have my imperfections. I’ve been on quite a personal journey, from being a solo hacker-developer to leading a company of 100+ people where EQ is highly valued. I still have much to learn, not least from many of my amazing colleagues. The feedback I frequently receive from them is a great help. For the occasions when I have been emotionally tone-deaf in my dealings with you, I can only apologise, and humbly request that you grant me the same freedom to fail that we aspire to give to all our Swiggers. Apologies that you have been given an inaccurate picture of our structure at PortSwigger. We actually don’t claim to have a flat structure. We have teams with team leaders, organised into tribes led by tribal elders, and I lead the whole business. What we do say is that we minimise hierarchy, and this means that we don’t really care about job titles, we don’t impose swimlanes on people based on their level of experience, we view leadership as being servant-based (enabling others to succeed) as well as being often shared and contextual, and we make decisions in a collaborative way. But with 100+ people, we of course can’t be a pure democracy or give everyone complete autonomy. That would be a recipe for anarchy and failure. I'm sorry that you are not finding your work at PortSwigger fun. The idea that fun is an important factor at work is indeed a cornerstone of our culture. It plays out in various ways: we work on fun and interesting challenges; we look for ways of working that are enjoyable; we are surrounded by fun people who are nice to each other; we have fun at social events and all-hands meetings alongside getting the job done. Having fun at work isn’t about everyone getting to decide what work they take on. If that happened, we would quickly become misaligned, pulling in different directions, and ultimately fail as a business. That wouldn't be fun. Dafydd Stuttard
