With most of the UK’s economy on its knees as a result of the havoc caused by COVID-19, one bright light in the darkness is the booming tech sector and the rise in cyber companies.

How’s this for a stat: During 2020 UK tech companies raised over $15bn in investments, which is more than their German and French counterparts combined.

As a subset of the broad “tech” category, cyber security is a huge part of that UK growth and will continue to see increasing investment as organisations from one-person outfits to PLCs look to fend off near constant attacks on their systems.

Supported by massive infrastructure projects, such as The Golden Valley Development in Cheltenham, cyber companies are well-placed to spearhead the UK’s economic recovery from corona virus-induced harm.

In no particular order, here are some of the leading cyber security firms to watch in 2021:


Delivering secure messaging and protection for stored data, Pryvate addresses the threat of criminals who pose an ever-present threat to a safe and properly functioning internet. Since 2013 the company has joined individuals, organizations and NGOs in their work to provide secure communications platforms. The company has no access to any of its users’ encryption keys, there is no “man in the middle”, making it impossible to leak, hack, collaborate or give away keys. All communications are device-to-device, it is the Pryvate app on your device that encrypts your voice, video or text, and the Pryvate app on the recipient’s device that encrypts theirs. No records exist of any communications and the encryption key is discarded. In addition to the app Pryvate provides an SME and enterprise version of its software providing a range of services including privacy compliance, closed user groups and audit logs.

Black Dice

A spin out from GCHQ’s Cyber Accelerator programme, BlackDice’s AI powered cyber security solution helps telecoms operators create new services, reducing churn and increase revenue.

Features of the software include patented device fingerprinting cyber technology capabilities to prevent device hacking. It also provides threat intelligence, matching existing threats to system vulnerabilities, automatically taking remedial action against compromised apps, devices and websites.

BlackDice protects devices from external threats, sets rules, filters content, and much more to create an all-round safer environment over wifi networks and mobile data, any network, anywhere. Its proprietary can be used with any router/gateway, using minimal resources, connecting to cloud services providing 24/7 protection to any network, anywhere.


Angoka is an IoT (Internet of Things) security startup which serves sectors including Smart Cities, Industry 4.0, autonomous vehicles and critical infrastructure, providing hardware solutions for businesses operating in those industries. It is one of the cyber companies with a clear focus on M2M (machine to machine) communications; Angoka uses its own patented technology developed to create and maintain trust between physical devices, thereby enabling completely secure communications for users even over “zero trust” networks. The firm, which is based in Northern Ireland, has its IoT security solutions embedded directly into users’ hardware, creating secure device integration and communication, eliminating the need for continuous security updates.


Malicious data breaches are often caused by stolen or compromised credentials. Keyless gives companies the ability to manage the risks that come with the storage of sensitive information, such as passwords, biometric data and crypto keys. Keyless’s zero-knowledge biometric authentication software uses cryptographic technology to address these concerns and provide businesses with peace of mind that the data in its care is secure and remains private.


Darkbeam’s solutions, built on its own proprietary persistent crawler, allow users to weigh up security risks and standards for not just their own assets, but those of any digitally connected partners. This delivers real-time “hacker’s eye” visibility of any potential vulnerabilities that could be exploited, together with any surface data breaches or stolen credentials. Darkbeam’s solutions don’t involve long and intricate implementation and can be used through a regular browser.


Nanotego delivers self-aware, autonomous cyber security defence capabilities to billions of attackable devices. Its solution offers a uniquely effective approach to cybersecurity by establishing “situational self-awareness” for each computing node. By monitoring deep layer data streams from device components, system and application processes, anomalous behaviour is identified, giving each device the ability to fend for itself by autonomously launching countermeasures in near real time without relying on connectivity, virus signatures or human interaction.

Threat Essentials

Threat Essentials is a new threat intelligence platform designed to turn cyber security into a strategic risk management tool and business asset.

Their mission is to predict, prevent and combat malicious activity and emerging cyber threats before they first surface. They do this by monitoring and analysing activity on the deep dark web, watching how threat actors behave. Threat Essentials want organisations to proactively manage their cyber security threats and minimise risk so they can reach their full business potential.
