Security | Threat Detection | Cyberattacks | DevSecOps | Compliance

For years, security vendors have treated SIEM and XDR as two distinct pillars of their security stack - one built for broad log visibility and compliance, the other designed for high-fidelity detection and rapid response. However, as hybrid environments expanded and attackers began exploiting identity, endpoint, cloud, and network surfaces simultaneously, those boundaries blurred.

With only a few days remaining in 2025, we sat down with Sundhar Annamalai, Chief Strategy Officer, LevelBlue, to discuss some of the major inflection points facing the cybersecurity industry in the coming year.

As 2025 closes and we look toward 2026, the cybersecurity industry is bracing for radical changes that go beyond just intensifying existing problems. To help prepare for these new challenges, at least as much as is possible, a few of our experts weigh in on the defining shifts across the security landscape, from the evolution of nation-state tactics and the crisis in core internet infrastructure to the necessary, strategic pivot toward cyber resilience and identity-centric defenses like Zero Trust.

As 2025 comes to a close, it’s the perfect time to look back at the last year to see what LevelBlue as a company accomplished. We can point to the thousands of clients that we helped keep secure, more than a few acquisitions that have resulted in the creation of LevelBlue as the world’s largest pure-play MSSP company and pulling it all together are the accolades from industry analyst firms and the media showing the extent and depth of our expertise.

At this time last year, LevelBlue asked its experts to offer up some thoughts on what the coming year, 2025, would bring. So, with a year of hindsight, let’s keep ourselves honest and take a look to see what we got right and where we were a bit off. December 2025.

In 2026, one theme will become impossible for security and infrastructure leaders to ignore. The architecture that once secured the enterprise no longer aligns with how the enterprise actually works. Users are everywhere. Applications are everywhere. Data is everywhere. Threats are everywhere. What is not everywhere is consistency.

For the second consecutive year, LevelBlue has been named a top-ranked Managed Security Services Provider (MSSP), placing fifth on the prestigious MSSP Alert’s Top MSSP 250 list for 2025. “LevelBlue is the world’s largest pure-play Managed Security Services Provider (MSSP), offering AI-driven, cloud-native cybersecurity solutions across managed security, MDR, offensive security, strategic advisory, and incident response,” MSSP Alert said.

Frost & Sullivan has recognized LevelBlue as a Growth Index leader in the just-released Frost Radar: Managed Detection and Response, 2025. Companies plotted on the Frost Radar are the leaders in the industry for growth, innovation, or both. This recognition indicates LevelBlue is a leader in Managed Detection and Response (MDR) and an organization others should look to when deciding how to best solve their cybersecurity needs.

LevelBlue is redefining what clients and partners can expect from a managed security provider. Through a new partnership with Tenable, a world-class leader in vulnerability management, LevelBlue is introducing unlimited, enterprise-grade vulnerability scanning for all clients and partners using the LevelBlue USM platform — included at no additional cost.
