The challenge: Battling noise and threats
In the logistics industry, security risks are an everyday challenge. With a vast digital footprint — 400 users, 35 primary servers, and a replicated off-site data center — Mid America Overseas faced relentless cybersecurity threats.
Michael Mierwinski, CFO and CIO at Mid America Overseas, highlights a few of the most prevalent challenges his team faced on a daily basis: “We have several phishing and impersonation attacks via fraudulent emails targeting employees almost daily. And the relentless scanning from suspicious IPs attempting DDoS attacks was creating excessive noise and diverting IT resources from strategic initiatives. Not to mention that outdated free IP threat lists are often stale or overly aggressive, disrupting legitimate traffic.”
MAO needed a dynamic, automated solution to filter out malicious traffic without burdening their IT team.
Discovering a curated, real-time shield
After evaluating multiple solutions, MAO discovered CrowdSec through Sophos Firewall’s third-party threat intelligence integration. Seeking a more robust alternative to stale, free blocklists, they found CrowdSec Blocklists stood out for multiple reasons.
High-quality, curated threat intelligence: Unlike static blocklists, CrowdSec’s real-time IP reputation system blocked known malicious actors without false positives.
Seamless integration: Easily deployed via Sophos Firewall, requiring zero manual maintenance.
Noise reduction: In just one month, CrowdSec blocked 40,000+ malicious attempts, slashing unnecessary alerts.
CrowdSec gave us the confidence that threats are being stopped at the firewall level, without us having to manually analyze logs. It just works.

A firewall that works smarter, not harder
With the CrowdSec Blocklists in place, Mid America Overseas now operates with an always-on security shield, ensuring smooth, secure global logistics for their clients. Since deploying CrowdSec, MAO has experienced:
- 40,000+ malicious IPs blocked monthly, reducing attack surfaces automatically
- Zero operational disruption, with legitimate traffic flowing uninterrupted
- IT time reclaimed, with no more manual log reviews, freeing staff for strategic projects

This report was generated by Sophos.
In just one month, CrowdSec blocked 40,000+ malicious attempts at our firewall, eliminating noise and freeing our IT team from manual log analysis. For a global logistics company like ours, that’s 40,000 fewer risks to customer data, shipment systems, and operational continuity.
Michael and the MAO team also plan to deploy the CrowdSec Security Engine, CrowdSec’s behavior-based IDPS, to contribute threat data back to the CrowdSec Network and further strengthen their global defenses.
