Common Questions

Frequently Asked Questions

Everything you need to know before reaching out to us.

We Have an Active Breach Right Now. What Should We Do?

Contact the SourceMash Incident Response team immediately. Our specialists rapidly assess the situation, establish a secure communication channel, and provide immediate containment guidance to help limit business impact. Avoid shutting down affected systems, removing malware, or reimaging devices, as these actions may destroy critical forensic evidence. Preserving evidence during the early stages of an incident significantly improves the effectiveness of the investigation and recovery process.

What Is an IR Retainer and How Does It Differ from Ad-Hoc Incident Response?

An Incident Response (IR) Retainer is a proactive service agreement that provides guaranteed access to security responders under predefined service levels when an incident occurs. Unlike ad-hoc engagements, which often require procurement and scoping during a crisis, retainers enable immediate analyst engagement and accelerated response times. Retainer clients also benefit from incident readiness assessments, tabletop exercises, and custom response playbooks that improve overall security preparedness.

How Long Does a Threat Hunting Engagement Typically Take?

The duration depends on the scope of the engagement. Targeted hunts focused on a specific threat actor, technique, or indicator generally take several business days, while broader environment-wide hunts may extend over multiple weeks. Organizations using managed hunting services benefit from ongoing threat investigations, continuous detection improvements, and regular reporting designed to adapt to the evolving threat landscape.

Do We Need to Be an MDR Client to Access These Services?

No. SourceMash delivers Cyber Threat Hunting and Incident Response Services as standalone engagements, allowing organizations to access expert support whenever needed. While MDR clients benefit from deeper visibility and historical environmental context, businesses can engage SourceMash independently for incident response, proactive threat hunts, ransomware investigations, forensic analysis, or security assessments without any ongoing service commitment.

Will SourceMash Help With Regulatory, Legal, and Cyber Insurance Requirements?

Yes. SourceMash supports organizations throughout the regulatory and compliance process following a security incident. Our team assists with breach notification assessments, evidence collection, documentation preparation, regulator communications, and cyber insurance reporting requirements. We also provide detailed forensic findings, incident timelines, and remediation documentation that help organizations meet compliance obligations and support insurance claims efficiently.
