  • The Departments of Defense, State, Homeland Security, Health and Human Services, Veterans Affairs and Justice, including the Federal Bureau of Investigation;

ManTech International operates a website at, through which it provides information on its various products and services. The Company, however, does not operate an online sales channel.

With the majority of ManTech International’s business coming through government contracts, much of the Company’s business is secured by a devoted sales team through competitive government tenders and auctions. The Company employs a team specialised in dealing with government agencies.

The nature of ManTech International’s business does not lend itself to the use of channel partners, such as resellers and sales agents, with the majority of the Company’s contracts coming through official government channels.

Customer Relationships

While ManTech International has an online presence, its business model does not allow for it to simply provide solutions on a self-service basis. The Company has a devoted sales team that manages the process of bidding for and securing government contracts, which requires that the Company be compliant with a series of official regulations.

ManTech International deals directly with its customers, both public and commercial, consulting with them over a period of time in order to provide a bespoke solutions spanning its entire range of services and products.

ManTech International also provides ongoing support to its customers, with customers able to contact the Company directly through email and phone channels. The Company also operates social media accounts with Twitter, Facebook and LinkedIn.
