Automated incident response – efficiency at scale

No matter how robust your email security measures are, some threats will inevitably bypass initial defenses. Whether it’s a sophisticated phishing attack or an emerging malware variant, the ability to swiftly detect and respond to post-delivery threats is critical for limiting damage and ensuring business continuity. This is where automated incident response becomes a game-changer and an essential part of your email security.

The need for post-delivery threat mitigation

Organizations often rely heavily on pre-delivery email security to filter out the majority of attacks. However, the reality is that even the best defenses cannot catch everything. When threats slip through, security teams need to act fast. Delayed or inefficient responses can allow attackers to move laterally, exfiltrate sensitive data, or disrupt operations.

A proactive post-delivery threat mitigation is essential to:

• Contain potential damage.
• Minimize the spread of malicious content.
• Protect end users and critical data.

Unfortunately, many organizations struggle to respond effectively due to resource constraints and manual inefficiencies.

The challenges of manual incident response

Manual incident response is common but has a number of drawbacks:

Time consuming: Manually remediating even a single phishing email can take hours, especially when it involves identifying all affected users, quarantining messages, and conducting follow-ups.

Resource intensive: Limited IT staff often cannot keep up with the volume of threats, leading to delays in response.

Prone to errors: Human oversight increases the risk of missing key indicators or failing to act quickly enough to prevent further spread.

Why automated incident response is the solution

Automated incident response transforms post-delivery security by addressing these inefficiencies. With automation, organizations can minimize risk by automating the detection and remediation of threats before they cause widespread damage. This means accelerated remediation that will significantly reduce the time between detection and response. It will allow you to scale effortlessly to handle large volumes of incidents, ensuring protection even for resource-constrained organizations. All while improving accuracy and minimizing the risk of human error.

Core components of automated incident response

While the specifics of automated incident response systems can vary, effective solutions often include:

Threat hunting and investigation tools: IT teams should be able to proactively identify, analyze, and mitigate potential threats within an organization’s environment before they cause significant harm. It involves a combination of human expertise and advanced technology to search for signs of malicious activity. For example:

• Analysis of user-reported messages
• Crowd-sourced intelligence based on incidents created by other organizations or your own teams
• Detailed insights into attack patterns and affected users, enabling IT teams to assess the full scope of incidents.

Remediation: Provides the ability to automatically claw back all malicious emails and neutralize potential threats across all affected inboxes. Identify the full scope of the attack, including all impacted users and mailboxes, and permanently remove malicious emails directly from user inboxes.

Automation: The fully automated incident response will streamline repetitive tasks with rule-based actions, ensuring consistency and accuracy while reducing the manual effort required from IT teams. For example, build custom response playbooks to completely automate your incident response process by defining a trigger, determining conditions, and assigning the desired actions through a simple user interface.

The ROI of automation

Automated incident response delivers measurable value. It ensures faster response times, as immediate actions prevent threats from escalating. It minimizes risks by reducing the window of exposure and potential damage. Operational efficiency is achieved by freeing IT teams to focus on strategic priorities instead of repetitive tasks. Additionally, cost savings are realized through lower IT operating costs by reducing the manual workload required to manage threats.
