Assured Clarity Limited
We are a global consultancy firm that specializes in Digital Risk Management and Data Privacy/Data Protection, while also ensuring robust Cyber Security measures for our clients. Beyond regulatory compliance with laws like the EU GDPR and UK Data Protection Act 2018, we provide subject matter experts to help organizations build cyber and organizational resilience. We collaborate with clients to achieve relevant industry standards and accreditations that demonstrate their commitment to maintaining a robust compliance posture, including ISO 9001, ISO 14001, ISO 20121, ISO 22301, ISO 27001, ISO 27701, ISO 42001, as well as HIPAA, SOC2, and PCI DSS 4.0 Audits. We consider Education, Awareness, and Training as fundamental, recognizing the importance of the "human factor," and have developed our Kautiio platform to deliver simulated phishing attacks. We assist companies in identifying risks to their business, breaking down internal silos, and conducting comprehensive risk assessments. We can perform external and internal network scans, pressure testing infrastructure and architecture security. Subsequently, we work with clients to design an integrated strategy for managing these risks, building trust throughout their organisation. Beyond our individual technical competencies, our company culture ensures a positive and pragmatic approach, delivering a safer and more resilient workplace. Until recently, with the European General Data Protection Regulation acting as an influence, Information Security, Data Privacy Management, and Cyber threat defence were typically left to the IT department, but primary research concludes that people within an organisation are its weakest link. The new EU AI Act is another area where we are now helping organisation assess and categorise their 'Artificial Intelligence' risk. Through education, awareness, and training, we have an opportunity to work with you to build a robust organisation and create transformational change.

You're normal world changes radically to one where you're forced to confront the sobering realities of what it feels like to be a victim of Cyber Crime. You're thrown into a crisis situation, firefighting for survival. Clients walk out the door with their revenue, as their trust in you is shattered. Data breach lawyers persistently threaten millions of pounds in data-loss claims and GDPR looms with fines of 4% of turnover or €20 million, whichever is higher. You're forced to pay for a forensic examination of what happened and learn how much data was stolen. The more that's stolen the higher and higher the fines become, to per person is normal. And to top it off you have to publicly disclose it all to the ICO. Competitors leverage the news to lure your customers away promoting the attack to all who'll listen. And desperate calls to insurers confirms your fears, that data breach losses are not covered. Helpless to retaliate against a hacker you cannot see and labelled as Guilty of Losing Client Data, instead of the victim. This is the world we live in, and why we developed the HALT Framework. HALT is an acronym for, Harden, Automate, Limit & Train, and is a Technological and Psychological solution to the ever-growing threat of Cyber Crime. Designed to mitigate the Financial Exposure to Data Loss Prosecution and protect your Business, your Reputation and your Credibility, and get your Bank, your Insurance Company and your Professional body to support you with money, insurance pay-outs and help even if you do get attacked.

We work together to pool our knowledge and skills to provide your business with the best service at a competitive rate.

Our core principle is to provide you with the knowledge and capability so that you can fully operate after our work with you has finished. As an example, an important part of our approach is to provide training during the engagement - either as we are undertaking the work or with formal classroom training courses. We work in all business sectors including the public sector (local government, NHS and central government), financial services (e.g. banking retail and investment), not for profit (education, housing and charities). We work with all sizes of organisations from very small SMEs (e.g. 5 people) to FTSE 100 companies. We are used to dealing with staff at all levels in organisations include Boards, Audit committees and C level executives. We often start work on our engagements at very short notice – typically within a few days. Our engagements are of any size from one day upwards and include part time work – for example a day a month.
