Welcome to the most exclusive membership in cyber security.

You are here: Home / Welcome to the most exclusive membership in cyber security.


In this inhospitable and unpredictable digital climate, it is all too common for security professionals to feel unsupported and lonely while trying to defend their organisation from the rising number of increasingly sophisticated cyber threats. This is why here at Quorum Cyber we wanted to create ARQCUS, a community that will ensure no-one tackles the cyber security challenge alone.

Federico Charoksy, Founder & CEO, Quorum Cyber

ARQCUS is ...

An exclusive membership which provides timely and carefully curated information, advice and support for you as an individual by creating a forum of peers across a small selection of our customers’ organisations. It’s a safe and shared space for you to exchange lessons and ideas with your counterparts in other companies and industries.

Each member organisation may have two nominated participants.

We will be deliberately restricting entry to ARQCUS to 10 customers in year one, ensuring that we deliver a tailored executive offering.


ARQCUS will address the following challenges that many senior cyber security leaders face today:

  • Overwhelmed by too much information coming in from too many sources
  • Constantly trying to keep up to date but never having quite enough time
  • Lack of confidence that your knowledge is where it needs to be to stay well informed on current and emerging threats
  • Feelings of isolation and loneliness arising from the responsibility of having to keep your organisation safe and secure, and the consequences of failing to do so
  • Fear of sharing concerns with peers and colleagues.


Many organisations feel like they are tackling the cyber security challenge alone without dedicated professional support or access to the crucial information they need to adequately protect their IT estate, their data, their customers and their business. They may not have the resources, know-how, expertise and experience to proactively achieve cyber resilience.

As an ARQCUS member, you’ll learn about evidence-based best practices, insights into hot topics and the latest developments in the world of cyber security. You’ll receive threat intelligence you can use to reduce risk for your organisation, ahead of the curve. Membership also gives you the opportunity to share knowledge with peers in your industry and with market-leading businesses in other sectors.

As a member of ARQCUS, you will receive:

Access to experienced strategic advisors from Quorum Cyber’s advisory board

Quorum Cyber’s board comprises individuals with extensive experience of cyber security, working with and advising UK Government and regional governments

As part of the membership, you will have an opportunity to schedule a quarterly one-hour online meeting with a member of the advisory board. For organisations wanting an update on global threat, geopolitical activities or input to a cyber strategy, these sessions will be invaluable and of strategic value to your organisation. As a member, you can decide what you want to focus on during your time


Annual strategy session by Quorum Cyber CEO/C-suite

As a customer you may already have met and spoken with our CEO and C-suite. What this offers our members is a guarantee that you can access time with them and connect them with your own C-suite or board. In other words, it is the ability to have a more strategic approach in that time with the Quorum Cyber C-suite rather than an occasional ad-hoc catch-up meeting.

Monthly cyber briefing roundtable with ARQCUS members

As an ARQCUS member you will have an exclusive invite to a monthly cyber briefing focused on current activities and threats happening that month. It is an opportunity to stay up to date on recent events and to also share and learn from other members. The briefings will run with Chatham House rules and not be recorded.

Invites to in-person executive cyber strategy sessions

As a member you will be invited to a minimum of three in-person cyber strategy dinners a year. These will allow more engagement with, and a chance to speak in-person with, Quorum Cyber senior management and other ARQCUS members. We will also invite the Head of Threat Intelligence or other key experts from within Quorum Cyber and/or Microsoft to these occasions to allow direct access to senior experts.

Company-specific threat intelligence

You will receive a company-specific threat intelligence report every six months. In addition, you can request two further reports on specific areas of interest to you at any time during a 12-month period.

All of these services will be supported by a ‘concierge’ service where we will check in regularly and ensure that you are maximising the value of your membership. You will also have access to a members’ only dedicated email to ensure a rapid response to any queries but also to allow any issues to be escalated quickly to Quorum Cyber’s leadership team.

Be part of the most exclusive membership in cyber security.

You don’t have to tackle cyber security alone. Partner with our experienced professionals and gain access to valuable insights, the latest developments and the opportunity to share knowledge and lessons with your peers in other industries.

We look forward to welcoming you to ARQCUS.
