About Us
Having spent many years supporting some of the world’s leading corporations, consultancies, and governments, we are a team of highly experienced contractors available to solve your offensive security challenges.
As organizations, your security maturity is directly related to the quality of your security testing program. As security service providers, your consultancy relies on personnel. In both instances; the human element is critical.
As an alternative to using junior resource as many consultancies do, Atlan Digital only provides highly experienced consultants to deliver on engagements. These resources are specialists in the relevant domains.
We only field contractors that have a minimum of 5-10 years experience having delivered at the highest level of offensive security consulting.
Whether it is our contracting leads for a project based engagement, or cross disciplinary team of four contractors that you seek for a challenging multi-month end-to-end engagement, or an ongoing Penetration Testing as a Service (PTaaS) offering - we can deliver world class outcomes.
