"Expertise and Empathy with Compliance"
What do you like best about Cognisys?

I like our experience with Cognisys. They have been very prompt and helpful, especially in figuring out how to best contextualize compliance requirements with our business context. Their expertise is deep, and they demonstrate deep empathy with us and the stage of our journey. We've thrown a ton of questions and clarifications at them, and they've always been prompt, precise, and helpful. Their focus on pointing out every detail that matters and showing how we can use Vanta's features to reduce the burden of compliance substantially is something I truly appreciate. This allows us to stay true to the compliance requirements without becoming overbearing. I also appreciate their deep expertise, healthy respect for compliance, and great empathy for customers.

"Invaluable ISO 27001 Guidance and Fantastic Support"
What do you like best about Cognisys?

I found Cognisys's guidance through the ISO 27001 audit journey invaluable. They helped our small team focus on the right tasks at the right times with their knowledge of the Vanta platform. Their group and individual workshops are great, and they do a great job of clearly breaking down audit requirements. I also appreciate how Cognisys tailors their advice to individual business needs and their impressive knowledge of the digital sector. They helped us understand where our organisation is exposed to risk and streamlined our operational efficiency, leading to better documentation and risk mitigation. I also enjoy working with their team; they're a pleasure to collaborate with and have a deep understanding of the subject matter. Review collected by and hosted on G2.com.

What do you dislike about Cognisys?

The only thing I would change would be a more individually tailored and clearer timeline. Not all companies are equal in size and resources - and a more individual approach to the various steps and tasks. But I understand that this might not be feasible. Review collected by and hosted on G2.com.

"Streamlined Certification with Great Support"
What do you like best about Cognisys?

I appreciate Cognisys for their ability to streamline the process and help ensure that our platform meets the stringent certification requirements for ISO 27,001 and SOC 2, providing actual security. They are very good at helping us understand the Vanta platform and ensuring our team works efficiently within its constraints, preparing us well for our ISO 27,001 independent audit. I also like the personal service they provide, which is very helpful as our team navigates security implementation. Additionally, the combination of their personal service, technical awareness, and depth of their team is supportive. Review collected by and hosted on G2.com.

What do you dislike about Cognisys?

Setting expectations up front about the level of commitment and complexity of achieving ISO 27001 and SOC2 would be helpful. Once we understood the resources that we would need internally and had committed those resources, they were a good partner to guide us rather than doing the work for us, which is important for ISO 27,001 anyway because, ultimately, it's a standard for your own company's security.

"Essential Partner for Security Compliance"
What do you like best about Cognisys?

I really appreciate Cognisys for being incredibly supportive, always willing to help us and answer our questions. They prepared all the paperwork and guided us step by step for our ISO 27,001 and SOC 2, which gave us massive value since many clients required those accreditations. The team at Cognisys is great and nice to work with, and the way they present the work is just the best. I find it incredibly useful that Cognisys ensures we are not muddling through confusion, as their expertise provides clarity. Their frequent experience in the field is invaluable, and they've implemented substantial improvements we never had before, like using password keepers and ensuring proper access checks. I'm thoroughly pleased with the partnership. Review collected by and hosted on G2.com.

"Exceptional ISO compliance partner — zero nonconformities across three audits"
What do you like best about Cognisys?

Cognisys delivered outstanding ISO compliance consultancy from start to finish. Enda Maguire was hands-on, proactive, and highly available throughout — from initial gap analysis to audit day. The team drafted and uploaded all required policies to Vanta, prepared comprehensive written meeting summaries after each session, and meticulously tracked every action item. We went from 59% Vanta completion to fully audit-ready in just a few weeks. Review collected by and hosted on G2.com.

What do you dislike about Cognisys?

Very little to criticise. There was a last-minute substitution of a consultant on audit day, but it was communicated promptly and handled professionally. Review collected by and hosted on G2.com.

"Cognisys Made Cyber Essentials Clear, Structured, and Stress-Free"
What do you like best about Cognisys?

What we liked best about Cognisys was their combination of deep expertise, responsiveness, and practical support. They were very knowledgeable about both Cyber Essentials and Cyber Essentials Plus, but just as importantly, they explained everything clearly and guided us through the process in a way that felt structured and manageable.

They were also highly responsive whenever we had questions, and their approach gave us confidence that we were focusing on the right areas. Overall, they made what could have been a stressful and complex process much smoother, more efficient, and easier for the team to handle. Review collected by and hosted on G2.com.

What do you dislike about Cognisys?

There was very little to dislike about working with Cognisys. Our experience was very positive overall. If anything, the process naturally requires internal time and coordination on our side, but Cognisys made that as straightforward as possible through clear guidance, responsiveness, and a very practical approach. Overall, they were professional, supportive, and easy to work with throughout. Review collected by and hosted on G2.com.

Response from Aston Smith of Cognisys

It’s great to hear that our team’s expertise, responsiveness, and practical approach helped make the process feel more manageable. We’re especially pleased that the experience not only supported you in achieving certification but also helped build confidence along the way.

"Empowering Compliance and Growth with Stellar Support"
What do you like best about Cognisys?

I use Cognisys to obtain our compliance certifications for SOC 2, ISO, and cyber essentials. I appreciate how Cognisys has enabled us to work with enterprise organizations by meeting these essential compliance requirements. I find the certifications set by Cognisys to be crucial in establishing our organization's security posture, as security, compliance, and trust are foundational for us. The sessions with Cognisys's experts on certifications have been incredibly helpful, especially since I don't have a compliance background. It's been great to get direction and support when steering in the wrong direction. Additionally, I enjoy the engagement with technical experts for certifications and their assistance in utilizing Vanta to its full potential. Furthermore, the strong Slack channel with the Cognisys team makes it really easy to communicate and get quick responses, which I find very effective. Overall, I really enjoy the engagement and have even expanded to using their virtual CISO to continue our partnership. Review collected by and hosted on G2.com.

"Agile and Reliable Consulting for ISO 27001 Certification"
What do you like best about Cognisys?

I really liked Cognisys's approach. They instilled confidence in the process and used a very agile methodology. They helped to understand all the requirements of the ISO 27001 certification, to map my weaknesses, and to find solutions much faster than would be possible alone or with another company. The journey they build is very assertive, clear, with a beginning, middle, and end. They have a deep knowledge of what the ISO certification requires, which made me feel confident to be approved. Furthermore, the service is very fast, practical, and efficient, with a communication channel that is always active. The organization of the journey as a whole is one of their strong points. Review collected by and hosted on G2.com.

What do you dislike about Cognisys?

There was nothing I didn't like. But I think it would be important to have people with knowledge in Portuguese. Review collected by and hosted on G2.com.

Response from Aston Smith of Cognisys

We’re especially pleased to hear that you felt our approach was efficient and well-guided from start to finish. We also appreciate your suggestion around language support. As we continue to grow, feedback like this is valuable in helping us improve.

"Essential Partner for ISO Accreditation Success"
What do you like best about Cognisys?

I really liked how Cognisys helped us with the ISO 27001 process, guiding us through it even though we initially didn't know much. They were very helpful in getting us accredited quickly. Working with Cognisys provided a structured method to identify potential risks and measure success, which was great for our business. Their guidance was incredibly valuable in setting up processes correctly from the start. The direct communication channel through Slack was excellent for quick interactions and ensuring tasks were on track. Also, the seminars or small meetings we had once or twice a week were very informative, especially with David explaining concepts in detail. Cognisys also helped us implement Vanta, a compliance platform that has been fantastic for tracking our compliance needs. Review collected by and hosted on G2.com.

What do you dislike about Cognisys?

Sometimes I would ask messages on Slack and they would be acknowledged very quickly. That was a common thing. They were always acknowledged. Rarely they'd be like, oh, let me check that for you. But then nothing would actually happen, and I would have to chase again. Again, very minor and they always got back to me. Review collected by and hosted on G2.com.

Response from Aston Smith of Cognisys

Thank you for taking the time to leave a review!

It’s great to hear that the support, structure, and guidance throughout your compliance journey have been valuable, and that the communication and collaboration worked well for your team.

We also appreciate your note around follow-ups on Slack. While we’re glad everything was resolved, we recognise the importance of closing the loop promptly and will continue to improve on this.

Thanks again for sharing your experience.

"Streamlined Compliance with Expert Support"
What do you like best about Cognisys?

I really like Cognisys’ collaborative approach, with regular touchpoints and consistent communication. Their overall support has been very helpful throughout. I also appreciate how quickly they were able to get up to speed from the start, helping us navigate regulatory requirements and stay compliant. The team’s expertise, especially around policies and the necessary tooling, makes the service genuinely valuable. Implementing our chosen ISMS, Vanta, was straightforward, and it was great to complement that with access to additional services for Vulnerability Testing. Their experience and know-how in delivering these solutions in the best way for our needs significantly sped up the process. Review collected by and hosted on G2.com.

What do you dislike about Cognisys?

They clearly are very busy, and sometimes this leads to some delays in communications, so perhaps they need to consider more capacity to remove bottlenecks? Review collected by and hosted on G2.com.

Response from Aston Smith of Cognisys

Thank you for taking the time to leave such a detailed review, we really appreciate your feedback.

We’re so pleased that your experience has been valuable and even helped you secure new work!

We also appreciate your honest feedback around bottlenecks. We’re actively hiring and expanding the team to help increase capacity and ensure we continue delivering the level of responsiveness and support our clients expect.

Thanks again.
