About

CovertSwarm is a modern offensive cybersecurity firm founded in 2020 and headquartered in London, with an additional office in Wilmington, Delaware. The company has pioneered a subscription-based continuous cyber attack model that represents a significant departure from traditional point-in-time penetration testing. Rather than conducting annual or quarterly assessments, CovertSwarm delivers relentless, full-spectrum assaults across an organisation's digital, physical, and social attack surfaces on a monthly subscription basis.

CovertSwarm holds CREST STAR, STAR-FS, and CBEST accreditations, placing them among the select group of UK firms authorised to deliver threat-led penetration testing for the financial sector and regulated industries. Their service portfolio includes web application penetration testing, network and infrastructure testing, cloud penetration testing across AWS, Azure, and Google Cloud, physical penetration testing, social engineering, breach and attack simulation, and ransomware attack simulation.

The company has grown rapidly since its founding, reaching an estimated team of 51 to 65 employees. CovertSwarm serves clients across finance, healthcare, cryptocurrency, SaaS, and public sector organisations, with pricing structured to start at less than the cost of a single internal security hire.
