When Ransomware Moves Faster Than You Can Blink

Ransomware no longer knocks at the door; it kicks it down. In 2023, ransomware payments hit an all-time high, exceeding $1 billion, a stark reminder of how profitable this crime remains for attackers. In 2024, estimated payments fell about 35% year over year to roughly $813.6 million, thanks in part to improved defenses and law-enforcement pressure. The threat hasn’t gone away; it’s evolved. Meanwhile, the 2024 Verizon DBIR shows extortion tactics (including ransomware) involved in roughly a third of breaches, and a 180% spike in vulnerability exploitation as a breach path, evidence that speed and scale still favor the attackers.

Attackers aren’t just brute-forcing their way in. They’re moving like trusted insiders, encrypting or erasing thousands of files across SharePoint, SMB, Google Drive, and Azure File Shares in minutes. Traditional security tools fire off one-size-fits-all alerts with no context, leaving analysts scrambling as data vanishes.

This is where Lightbeam’s new Ransomware Protection capability changes the game, by spotting the spike before it becomes a catastrophe, and cutting off the attack in seconds.

When Speed Becomes the Attacker’s Weapon

Ransomware isn’t about stealth anymore. It’s about velocity. Encryption bursts at machine speed while defenders are still parsing alerts. A departing employee can wipe out a customer folder on SharePoint before backups even kick in.

Legacy solutions were built for a slower world, with daily scans, scheduled backups, and manual triage. But today’s ransomware crews exploit that lag. By the time your team connects the dots, the damage is irreversible.

The only defense is real-time pattern recognition tied to human identity context, the ability to know what “normal” looks like for every user, and to instantly revoke access when activity veers into the abnormal.

A Behavioral Shield Against Ransomware

Lightbeam’s Ransomware Protection isn’t just another alerting system, it’s a behavioral shield woven directly into the Lightbeam platform. By observing how every user normally interacts with data across SMB, SharePoint, Google Drive, OneDrive, and Azure File Shares, Lightbeam learns each individual’s cadence over time. It understands what “normal” looks like for every identity, every file type, and every workflow.

When that pattern changes, the platform reacts instantly. Sudden bursts of encryption, deletion, or silent exfiltration trigger Lightbeam’s velocity-based anomaly detection, distinguishing human behavior from the unmistakable rhythm of ransomware or insider sabotage. Within seconds, it responds, pausing active sessions, revoking permissions, or isolating compromised identities—automatically or with a single click.

What makes these actions truly intelligent is that they’re not ad hoc reactions; they’re powered by policies defined within Lightbeam itself. Security teams can create precise rules that decide when to alert, when to enforce, and when to escalate. Every automated response aligns with your organization’s risk posture and governance logic, ensuring containment is never left to chance or manual triage.

Once the immediate threat is contained, Lightbeam provides the full story. Through the Data Identity Graph, it surfaces the complete context of the event, showing exactly which users, files, and systems were in the blast radius. A detailed, audit-ready report is then generated automatically, mapping timelines, actions, and compliance references so CISOs, auditors, and regulators have the proof they need at a glance.

All of this happens seamlessly within the Lightbeam platform, no extra agents to deploy, no bolted-on scripts, and no switching between dashboards. It’s ransomware defense reimagined: continuous, contextual, and completely automated.

What Sets Lightbeam Apart

1. High-Velocity Pattern Detection
   Monitors write, delete, and encryption rates against dynamic baselines, catching ransomware in action rather than after the fact.
2. UEBA Meets Governance
   Signals flow straight into policy-driven actions — revoke, snapshot, quarantine — without requiring manual scripting or external ticketing systems.
3. Cloud & SMB Coverage
   Works across modern SaaS and traditional shares: Google Drive, OneDrive, SharePoint, Active Directory, SMB.
4. Single Console Simplicity
   Analysts move seamlessly from detection to remediation within the same UI, preserving full forensic context.

Real-World Scenario

1. Ransomware on Google Drive — Stopped Mid-Attack

A marketing team at a global retailer suddenly experiences mass file encryption in their shared Google Drive workspace.

Problem: Within minutes, thousands of customer contracts and product images are renamed and unreadable — traditional endpoint protection tools haven’t fired an alert yet.

How Lightbeam Helps: The platform’s velocity-based anomaly detection flags an unusual encryption spike tied to one user’s session. Using behavioral baselines, Lightbeam recognizes this as ransomware activity.

Action Taken: Sessions are suspended automatically, permissions revoked, and a snapshot of every affected file is created before damage spreads.

Result: The attack is contained within 27 seconds. The CISO receives an audit-ready incident report with a full timeline for post-event analysis and compliance documentation.

2. Malicious Deletions on SharePoint — Insider Risk Contained

An employee leaving a financial services firm tries to erase customer data before exit.

Problem: Entire folder structures vanish from SharePoint—backups are hours away from running, risking permanent loss of regulated data.

How Lightbeam Helps: The platform detects a deletion-rate anomaly inconsistent with that user’s normal activity, triggering a policy-based automated response.

Action Taken: Lightbeam blocks the account, quarantines affected repositories, and creates recovery snapshots in real time.

Result: No data loss, full forensics for HR and legal, and a provable compliance record under GDPR and FINRA retention requirements.

Why This Matters for CISOs and Security Leaders

For CISOs and security leaders, the difference between disruption and resilience often comes down to how quickly they can act once ransomware strikes. Traditional tools flood analysts with one-size-fits-all alerts, burying real threats under noise. Lightbeam changes that equation. By correlating identity, data, and behavior in real time, the platform dramatically reduces alert fatigue, and security teams spend less time chasing false positives and more time containing verified risks.

This shift also strengthens operational resilience. Instead of reacting after encryption has begun, teams can pause user sessions or revoke permissions the moment velocity anomalies are detected. Attacks are contained before they spread, minimizing downtime and eliminating the need for ransom payouts.

Just as importantly, every response is automatically documented and mapped to relevant compliance frameworks, giving executives and auditors complete visibility into what happened and how it was resolved. In short, Lightbeam turns ransomware defense into an auditable, measurable process, one that helps leaders prove readiness rather than simply hope for it.

The Bigger Picture: When Data Governance Meets Ransomware Defense

Ransomware doesn’t strike in isolation. It thrives in environments where permissions go unchecked, data sprawls beyond oversight, and user behavior isn’t monitored in context. Each of these gaps, overexposure, shadow data, and lack of behavioral visibility, creates the perfect storm for attackers to move fast and quiet.

That’s why Lightbeam doesn’t treat Ransomware Protection as a standalone feature. It’s a critical layer in a much larger, connected framework, one that blends Data Security Posture Management (DSPM), Data Access Governance (DAG), and User & Entity Behavior Analytics (UEBA) into a single, identity-centric platform.

With DSPM, organizations first gain visibility, discovering and classifying sensitive data wherever it lives, across cloud or on-prem systems. DAG then builds on that visibility to enforce least privilege, ensuring every user only accesses what they need, nothing more. UEBA adds intelligence, learning behavioral baselines to detect when activity deviates from normal patterns. And when that deviation turns into a threat, mass encryption, deletion bursts, or data exfiltration, Ransomware Protection steps in to contain it in real time.

Together, these capabilities close the loop: from knowing your data to controlling access to detecting and responding instantly. It’s not a patchwork of tools, it’s a single, provable defense that unites security, privacy, and governance under one roof.

Control the Blast Radius Before It Grows

Attackers count on speed. Lightbeam takes it away. By detecting velocity spikes, isolating compromised identities, and tying every action back to identity context, Ransomware Protection helps organizations move from reacting to proving resilience.

The difference between downtime and continuity, ransom payment and recovery, is measured in seconds. Lightbeam gives you those seconds back.
