Splunk + XDR

Unified Security Operations for Complex Environments

Managed by Port53. Powered by You.

At Port53, our mission is simple — make enterprise-grade cybersecurity accessible, intelligent, and effective for every organization.

Our Managed Detection and Response (MDR) service is built on Cisco XDR, giving every customer the same best-in-class detection, triage, and response capabilities — open, integrated, and fully managed by our 24/7 SOC. For customers with larger, more complex environments or compliance-driven data needs, we extend that capability by integrating and optimizing Splunk — uniting the real-time power of XDR with the long-term analytics and data depth of SIEM.

The Same MDR Excellence, Built for Your Environment

Every organization gets the same level of Port53 MDR — proactive monitoring, automated response, continuous improvement, and human expertise behind every alert.

The difference comes in how we deploy and integrate that MDR service, based on your environment:

MDR with Cisco XDR

Perfect for small and mid-sized organizations, Cisco XDR delivers comprehensive coverage across endpoints, network, email, identity, and cloud. It’s open by design — integrating with leading third-party tools to give you unified visibility without complexity.

MDR with Splunk + XDR

In both models, it’s your environment, your data, your tools — we simply make them work smarter, faster, and better together.

For enterprises and multi-cloud environments with diverse telemetry or compliance requirements, Port53 integrates directly into your Splunk instance — optimizing ingestion, tuning correlation, and tying Splunk data back into our XDR workflows.
This creates a seamless bridge between SIEM data depth and XDR-driven response, managed end-to-end by our team.

Built on Cisco. Powered by Port53. Owned by You.

Our MDR service isn’t a black box. We don’t lock you into a proprietary stack or multi-tenant platform — we operate within your existing environment, aligning to your architecture, compliance policies, and business workflows.

We manage your Cisco XDR platform — fine-tuning policies, automations, and playbooks for your organization.

We optimize your Splunk instance — improving search performance, correlation logic, and retention strategy.

You keep full ownership and transparency — every alert, every dashboard, every response action stays in your ecosystem.

Why “XDR + SIEM” Makes Sense for Complex Environments

As organizations grow, so does the complexity of their data sources. Splunk complements XDR by extending MDR visibility across systems, applications, and cloud workloads that might sit outside traditional XDR telemetry.

Together, they deliver:

Full Visibility across hybrid and multi-cloud architectures.

Accelerated Detection & Response with contextualized XDR actions.

Compliance & Retention for regulated industries.

Advanced Analytics & Threat Hunting powered by Splunk search and enrichment.
