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

Pros

- Onboarding starts from offer, and carries all the way through past when you start. Onboarding sessions where you learn about being a Swigger, the culture, agile working, the product. All these things you would expect to be common sense, done to perfect execution. - A flat structure, that truly is flat, which is enhanced by the company's culture, mindset and ways of working - Fellow Swiggers who truly feel like part of a community of people who want everyone to do well, and not pretending that 'we are a family' type place - The company really enables you to succeed in your role, and wants to embed in you to become a Swigger as your first priority, rather than hitting targets/OKRs/KPIs from the get go. Understand why they are the way they are first, and becoming a Swigger at heart first before doing anything else. - The onsite premises and benefits are just a cherry on top. Free breakfast, lunch and snacks helps take a daily headache and cost away. Onsite gym with awesome shower facilities, with instructors to come in to teach boxfit, HIIT, yoga, pilates etc. Open spaces to enable that free-flow, incremental working mindset. SwigHouses, SwigBus - all to help you to relocate and commute to work if you need assistance,

Cons

- I don't think this company and culture would suit everyone. If you are very much used to that 'corporate' world, and hierarchical structure, Portswigger wouldn't be a place for you. - The company can flex in exceptional circumstances when it comes to working from home, but the 5 days onsite working is a must if you are looking to embed yourself to become a true Swigger and adopt the culture.

Pros

Free food is amazing, pay is way above average, order any book scheme is great

Cons

Emotionally fragile staff. Inexperienced HR (sorry "Culture") team. Leadership team subjugated to the CEO's decision making. "Feedback" culture not actually a thing, What happens when you hire a load of slightly above average people from a very restricted talent pool (of those people willing to commute to Knutsford every day), tell them they are all amazing, and pay them WAY above average? A group of people terrified of any change, suspicious of competent new joiners and willing to use emotional manipulation to deflect any criticism about their behaviour. Yes, Portswigger have cornered the market as a result of their feature rich bloatware, but their dysfunctional culture will not sustain them now that challengers are coming for their crown. The cash cow will soon stop dishing out milk. Currently the leadership team is the gang of eunuchs to the CEO's crown. The weekly all hands is the equivalent of the court jester's roundup, and no guys, your in-humour isn't that funny at all. The culture of feedback isn't actually a thing at all. What it means is they have a feedback tool, but you can't use it for everyone and some people won't receive feedback either through their diva status or the likelihood they'll throw a tantrum. If you prefer to operate in an environment based on facts and clam logical decision making, Portswigger isn't for you. If you thrive on emotional manipulation and drama, then you'll thrive there.

I am sorry to hear that PortSwigger didn’t work out for you. We know that it can be challenging for new people to adapt to a very different environment than they are used to, and PortSwigger certainly isn’t for everyone. Unfortunately, things don’t always work out, and it sounds like you made the right decision to move on and find something that is better suited to what you are looking for. I feel obliged to speak up on behalf of your former colleagues, since I don’t think you fairly represented them. Swiggers aren’t “slightly above average”. The vast majority of our people are exceptional: strong capability, energy, drive, and commitment to working well together. It’s no accident that our products have been so successful - that doesn’t happen without outstanding people working effectively. Our people are not in general averse to change. Over many years we have continuously evolved, reinvented ourselves, and transformed our products. We have dedicated teams who are focused on looking for new opportunities to change. We recognise that our humour isn’t for everyone, but it is authentically ours. We don’t take ourselves too seriously, and we seek out opportunities to bring humour and silliness into our work. We’re a diverse group of people and that obviously brings a wide range of approaches. The antics you observed aren’t centrally orchestrated - we gently encourage people to express their personalities and have fun together, and what you saw flows from that. They might not always get it right. Not everything that happens will delight everyone - on the odd occasion where a Swigger’s humour oversteps the mark, others will sensitively course correct them. But if someone really doesn’t get it and prefers a more sombre vibe, then they would probably be happier elsewhere. Your vivid metaphor of the CEO’s court of eunuchs made me laugh (and even wonder if someone will act it out at an all-hands meeting). But it’s nothing like the truth. Don’t mistake a group of well-aligned and mutually supportive leaders for a dictatorship. We have robust healthy debates within the leadership group, and our leaders support each other by providing constructive challenge. There is little concentration of “power” - I certainly don’t make decisions unilaterally. We do regard healthy and constructive feedback in all directions as critical to enabling our ongoing professional development and growth. This applies to everyone (certainly me). If you encountered a Swigger who rejected your feedback, then I apologise on their behalf - that isn’t the mindset we promote or aspire to. Finally, I must speak up for our Culture team. Agreed, they are emphatically not a conventional HR department, and we don’t want that. They are a group of exceptional people who truly care about supporting their colleagues to achieve the very best that they can, often working quietly in the background through personal interactions rather than heavy process. They provide world-class coaching, training, and support to Swiggers of every flavour right across the business. They help all of us to live out the values that we’re committed to, and I couldn’t be prouder of them, or the results that they achieve. Dafydd Stuttard - Founder and CEO
