Beyond Antivirus: Why Businesses Need SentinelOne for Complete Cyber Resilience

Modern cyberattacks move faster than human response and can easily evade legacy, signature‑based antivirus. From fileless malware and zero‑day exploits to AI‑assisted phishing and ransomware, modern threats demand prevention, detection and response that operate at machine speed. SentinelOne excels at this, which is why Simoda recommends it as the foundation of a resilient endpoint strategy.

Why Traditional Antivirus Falls Short in 2025

Traditional antivirus software relies on known signatures. The issue is that the attackers don’t. They can mutate payloads, live off the land, and exploit identities, often without dropping a file for antivirus to detect. With endpoints the most targeted foothold, organisations need autonomous protection that can spot and stop never‑seen‑before behaviours in real time, not after the damage is done and it's too late.

What Makes SentinelOne Different from Antivirus (and Other EPPs)

SentinelOne goes far beyond traditional antivirus by delivering AI-driven endpoint protection that detects and stops unknown threats in real time. Instead of relying on outdated signature-based methods, it uses static and behavioural AI models to identify malicious techniques, even if they’ve never been seen before. This means your business is protected against zero-day attacks, fileless malware, and advanced persistent threats.

Another key differentiator is agentic AI through SentinelOne’s Purple AI. This capability acts like an AI security analyst, allowing teams to ask natural-language questions and receive actionable insights instantly. It accelerates investigations, triage, and response, reducing tasks that once took hours to just minutes.

When an attack occurs, SentinelOne provides autonomous response and ransomware rollback, isolating infected endpoints, removing malicious artefacts, and restoring systems to a pre-attack state with a single click. Combined with Storyline technology, which automatically correlates telemetry across endpoints, identities, and cloud workloads into a clear visual narrative, security teams gain full context without drowning in alerts.

Independent evaluations back this up, proving its ability to deliver both depth and clarity in real-world scenarios.

How SentinelOne Endpoint Benefits Organisations

Faster Detection, Faster Containment, Lower Risk

Organisations that have been using Singularity Endpoint and Purple AI reported improved threat detection, reduced response times, and a lower likelihood of security incidents, outcomes that map directly to lower business disruption.

Measurable ROI

SentinelOne delivers strong return on investment through automation, analyst productivity gains, and reduced incident impact. In a climate of constrained security headcount, those efficiency benefits matter.

Built for the Whole Estate

The Singularity Platform spans EDR/XDR, AI SIEM and CNAPP from a single console and unified agent, with broad OS coverage and flexible deployment, which reduces the tool sprawl while helping to improve visibility.

SentinelOne vs. “Next-Gen AV”: The Platform Advantage

Many products label themselves 'next-gen AV' but SentinelOne takes it further. This is done by unifying prevention, detection, response and cross-domain telemetry into one platform, with agentic AI layered across the stack. That matters because modern attacks pivot between endpoint, identity, and cloud; stitching this context together in seconds. This can be the difference of an attempted cyberattack on an organisation just being a scare rather than a full-blown breach.

How Simoda Delivers SentinelOne as a Managed Outcome

Simoda combines SentinelOne advanced technology with a managed service approach to make sure that organisations are getting their desired outcomes and not just buying the tool. Our specialist cyber team delivers endpoint security with SentinelOne, backed by our SOC. It integrates adjacent controls like email security, web filtering, security awareness, MDR and configuration hardening for layered defence.

We have adopted a prevention-first mindset to stop ransomware and malware faster, then use automation and expert oversight to minimise noise and ensure rapid response. If you’re grappling with alert overload, limited skills, or board-level questions about risk, our team make sure that the approach has been tailored to your environment and industry.

The Takeaway: Endpoint Security Must Be Autonomous, AI-Powered and Outcome-Led

“Beyond antivirus” means behavioural AI, agentic automation, and platformisation across endpoint, identity, and cloud, which is precisely the reason why SentinelOne was recognised as a leader in the 2025 Gartner® Magic Quadrant™ for Endpoint Protection Platforms. Simoda's role is to turn that capability into a managed service with measurable outcome for your business.
