CAMBRIDGE, MASS. - May 30, 2006 - Mazu Networks, the leading provider of behavior-based network security solutions, today announced that the Boston Business Journal named the company as one of the Best Places to Work in Massachusetts for the second consecutive year. The annual award, now in its fourth year, recognizes the achievements in creating a positive work environment that attracts and retains employees through a combination of employee satisfaction, working conditions and company culture.
Mazu Networks was one of more than 300 companies to qualify for consideration, making the top 20 list in its size category based on the results of employee-satisfaction surveys taken throughout the spring of 2006. The positive responses from Mazu Networks employees sealed the company’s top ranking.
"Mazu Networks' success is directly attributed to the strength of our team," said Paul Brady, CEO, Mazu Networks. "We employ the best people in the industry and provide them with the work environment they need to succeed. Being acknowledged by our employees through this award is a great accomplishment for the company as it demonstrates the strong community of dedicated professionals that is Mazu Networks."
"For the fourth year in a row, our results validate how the creation of the right corporate culture can create powerful business advantages," said George Donnelly, editor for the Boston Business Journal. "Employees are proud to work for companies that are about more than just business."
The top 20 companies in four size categories - emerging (10-24 employees), small (25-100 employees), midsize (101-500 employees) and large (more than 500 employees) - will be profiled in a special supplement of the Boston Business Journal to be published on June 23, 2006.
A countdown celebration breakfast will be held on June 22 to announce the final rankings, including the top company in each category. Additional event information can be found online at http://events.bizjournals.com/2313.
The survey project itself was launched in January by the Boston Business Journal in conjunction with market research firm QMR Inc. of Wichita, Kansas. Companies were evaluated on the results of more than 20,000 employee-satisfaction surveys. Employees answered questionnaires that addressed such factors as their pride in the company, company encouragement, support and recognition of achievement and relationships with co-workers and supervisors. The results were analyzed and scored by assigning points to each question.
