Security software maker RSA Security and specialist security distributor Allasso are to part company next month, ending a two-and-a-half-year relationship.
RSA has already chosen Ideal, the UK arm of Bell Microproducts, to replace Allasso as its third UK distributor.
The two companies say they came to an amicable agreement after considering their individual plans for the future.
Steve Wheeler, UK sales manager at RSA, said Allasso had done a good job over the last two years in the corporate market, but that the vendor's new focus required a different distributor.
"The decision was as mutual as could be," he added.
With Ideal, RSA will gain access to approximately 4,000 resellers dealing in Microsoft products, whereas Allasso offered them about 800 specialist security players, said Bernie Dodwell, Allasso's sales and marketing director.
Commenting on the agreement Alex Tatham, vice president of global software at Bell Microproducts, said that Ideal had worked hard to win the business.
"Protecting data is what Ideal has always been about and our major move into the security business should be seen as an extension of our data storage, back-up and recovery," he said.
Dodwell said the change was not the result of a lack of sales. Allasso achieved between 24 and 30 per cent of RSA's UK business during their partnership period, with particular success in the corporate arena.
RSA's security products include authentication, digital certificate management software, web access management and developer toolkits.
But Dodwell did admit that both companies could benefit from new partners. "We sell to small and medium-sized enterprises through security resellers, but not to the Microsoft resellers," he said.
"This is not a business we are in and it is the right move for them because Ideal is Microsoft's biggest licensing partner.
"It was a mutual agreement because RSA could not give us the pan-European coverage we wanted," he added.
Allasso will take orders and supply RSA until 7 February.
