Revenue Management Firm Achieves Zero Dwell Containment with Xcitium

The Challenge

A Houston-based revenue management firm was relying on SentinelOne for endpoint detection and response. While SentinelOne is a capable platform, the company’s security team had growing concerns about their exposure to ransomware. Traditional EDR solutions operate on a detect-and-respond model — they identify threats after execution and then attempt to contain the damage. For a firm handling sensitive financial data, that gap between execution and detection represented unacceptable risk.

The company also faced increasing pressure from clients and regulators to demonstrate a stronger compliance posture. Their existing security stack checked the box on paper, but leadership knew that a detect-after-the-fact approach left them vulnerable to the kinds of ransomware attacks that were devastating mid-market firms across the financial services sector.

On top of the security concerns, the cost of their current EDR platform was climbing. License renewals, add-on modules, and the operational overhead of managing alerts were straining the IT budget without delivering the level of protection the business actually needed.

Key challenges included:

• Detect-and-respond gap leaving the organization exposed between threat execution and containment
• Ransomware risk that traditional EDR could not fully eliminate, especially zero-day and fileless attacks
• Compliance pressure from clients and regulatory requirements demanding a demonstrably stronger security posture
• Rising EDR costs without a proportional improvement in actual protection
• Alert fatigue from a platform generating noise without actionable containment

Our Approach

We conducted a cybersecurity assessment and vendor evaluation focused on solving the core problem: eliminating the dwell time window that ransomware exploits to encrypt systems and exfiltrate data.

Phase 1: Security Gap Analysis (Weeks 1-2)

We reviewed the firm’s existing security stack, endpoint protection policies, incident response procedures, and compliance requirements. The critical finding was straightforward — their detect-and-respond model meant that any novel or zero-day ransomware variant had a window of opportunity to execute before the EDR platform could react. For a financial services firm, even minutes of dwell time could mean encrypted client data and regulatory reporting obligations.

We documented the specific compliance frameworks the firm needed to satisfy and mapped those requirements against what their current stack actually delivered versus what it claimed on a datasheet.

Phase 2: Vendor Evaluation (Weeks 2-4)

We evaluated multiple next-generation endpoint security platforms, specifically focusing on solutions that could deliver containment at execution rather than detection after the fact. Xcitium’s zero dwell containment technology stood out because of its fundamentally different approach: rather than trying to detect threats faster, Xcitium contains every unknown executable in a virtualized environment at runtime. The unknown process runs in containment while the verdict is determined, meaning the endpoint and network are never exposed — even to brand-new, never-before-seen threats.

We compared Xcitium against the incumbent SentinelOne deployment and two other next-gen platforms on protection efficacy, compliance mapping, total cost of ownership, deployment complexity, and operational overhead.

Phase 3: Implementation and Migration (Weeks 4-8)

We managed the migration from SentinelOne to Xcitium across all endpoints. The rollout was phased to ensure zero disruption to business operations — Xcitium was deployed alongside the existing solution initially, validated in production, and then SentinelOne was decommissioned once the team confirmed full coverage and policy alignment.

We worked with the firm’s IT team to configure containment policies, establish reporting workflows, and ensure the platform was tuned for their environment. We also helped them document their new security posture for compliance audits, giving them concrete evidence of zero dwell containment rather than relying on probabilistic detection claims.

Results

The firm replaced their traditional EDR platform with a zero dwell containment solution that eliminated the ransomware exposure window entirely:

• 21% reduction in endpoint security spend by consolidating from SentinelOne to Xcitium with better coverage at lower cost
• Zero dwell containment deployed across all endpoints, meaning unknown executables are contained at runtime before they can cause damage
• Ransomware protection fundamentally improved from detect-and-respond to contain-and-then-determine, eliminating the execution-to-detection gap
• Compliance posture strengthened with documented zero dwell containment capability satisfying client and regulatory requirements
• Reduced alert fatigue as Xcitium’s containment-first model generates fewer false positives and eliminates the scramble to respond to active threats
• Improved security posture overall with a platform purpose-built for the threat landscape mid-market financial firms actually face

Client Feedback

“We thought our endpoint protection was solid until Catch Advisors showed us the gap between what our EDR vendor marketed and what it actually did when a zero-day hit. The move to Xcitium’s zero dwell containment was a game changer — we went from hoping our platform would catch threats fast enough to knowing that every unknown is contained before it can touch our systems. And we’re spending less to get there.”
