Build. Integrate. Secure.

Denim Group provides IT consultancy services encompassing all phases of the software development lifecycle including software development, application security assessments, development team training and consulting.

The Company's core expertise includes medium- and large-scale custom software development projects involving sophisticated programming solutions such as E-commerce, customer relationship management and portal development. Denim Group also integrates a wide variety of applications ranging from legacy systems to high-performance E-commerce sites and develops custom applications to pick up where the off-the-shelf software leaves off.

Denim Group developers are trained and experienced security consultants. Their working knowledge of the threats and countermeasures encountered in the application security arena, as well as development strategies that fit into the software development lifecycle, provide the level of expertise needed to develop, assess and remediate application source code.

Denim Group regularly hosts training seminars targeted at security professionals and developers to address secure development and auditing practices. As an element of Denim Group's security offerings, the Company also provides mentoring services through which security experts at Denim Group personally train security professionals and developers on-site.


Denim Group works with both commercial and government entities. Specific industry experience includes: financial services, banking, insurance, healthcare and defense. Denim Group also has strong competencies working with other industries including education, entertainment, retail and online commerce, construction, energy, high tech, and marketing/creative.

A Trained and Trusted Workforce

Unlike many technology consulting companies who regularly use contract labor, each member of the Denim Group team is a W2 employee. Having a tight core team allows Denim Group to invest in training and certifications resulting in unparalleled performance and consistency of execution. Additionally, every employee of Denim Group undergoes thorough background checks that cover criminal, lawsuit and credit history. A large percentage of these employees are also ex-military, and many have held the highest government clearances available.
