Definition
Partner specialization is when a partner focuses on specific customer segments, solutions or technical skills instead of trying to sell everything to everyone. Examples include a partner focused on healthcare, cloud security or one vendor's platform. Many vendor programs offer formal specializations that partners earn through training and proven customer work.
Specialized partners often win more easily in their focus area because buyers see them as experts. They can also charge more for services that need deep skills.
For vendors, specializations help match the right partner to the right deal. Requirements often include certified staff, customer references or completed projects. Programs differ on what they require and what benefits come with it.
In practice
A reseller earns a vendor's cloud security specialization, and the vendor's direct team starts bringing it into deals that need that skill.
