Windstream Holdings, Inc.’s WIN business segment — Windstream Enterprise and Wholesale — recently announced that it is launching SIEM (Security Information and Event Management) service to deal with the increasing security threats and regulatory compliances confronted by U.S. enterprises. SIEM is part of the company’s commitment to partner with firms to safeguard their data and respect customer privacy, ensuring long-term business relationship.Businesses are susceptible to criminal attacks from wide-ranging sources. Per a July 2018 study, sponsored by IBM Security and conducted by Ponemon Institute LLC, malicious attacks equate 52% of breaches in the United States. Together with human error and system malfunctions, these breaches cost U.S. firms $7.91 million per incident on an average. This includes costs for mitigation and loss of revenues due to customer churn.While Windstream’s SIEM service responds to threats detected in business networks, log retention is available for devices and can be archived for up to seven years. Notably, the comprehensive solution complements Managed Network Security service and services like SD-WAN and Managed Router. Windstream also offers DDoS Mitigation Service, PCI Compliance, SD-WAN Concierge, OfficeSuite UC and UCaaS/CCaaS to help businesses improve productivity.Furthermore, Windstream is seeking diversification from legacy telecom services to more enterprise and wholesale opportunities. It has made substantial investment to upgrade its network and product portfolio, including advances in SD-WAN capabilities and Cloud Core architecture.The company is realigning its wireless network toward a software-centric model to meet growing business demands and customer requirements. Windstream’s initiatives for sales improvement, cost cutting and pricing are laudable. Investments made in data center and fiber expansion should provide impetus for revenue growth in the coming quarters.However, Windstream’s shares have incurred an average loss of 20.5% compared with the industry’s decline of 4.7% over the past three months. It is to be seen whether such enhanced solution offerings can help the company improve its profitability. Windstream currently has a Zacks Rank #4 (Sell).
