Ontinue

Ontinue answers a question thousands of organizations should be asking out loud: we already pay for Microsoft E5 and the security suite inside it, so who actually runs it? Its managed detection and response is built natively on Microsoft Defender and Sentinel rather than bolting a proprietary stack alongside them, which means the licensing already on the books becomes the security platform and Ontinue's fee buys the 24/7 operation of it: monitoring, investigation, and response executed inside the Microsoft tooling, with day to day interaction happening in Teams where the customer's people already work. Microsoft has repeatedly recognized the firm among its top security partners, which is meaningful in a market where Microsoft native is often a marketing claim rather than an architecture. The economics are the elegant part: because the platform cost is already sunk into existing licensing, the total price of a mature detection capability often lands well below stacking a separate vendor's platform on top. The honest limits are the mirror image: for organizations not standardized on Microsoft, or running deliberately mixed estates, Ontinue is simply the wrong shape, and a stack neutral provider fits better. For committed Microsoft shops, it is the economically obvious shortlist entry.
