Cybersecurity Analyst · cover letter
[Date]
Dear [Hiring Manager],
Last year I rebuilt the alert-tuning logic in our Splunk SIEM and cut mean-time-to-detect from 41 minutes to 9, while reducing false positives by 63 percent so analysts stopped chasing noise. I would like to bring that same focus on signal over volume to the Cybersecurity Analyst role at [Company].
In my current SOC, I run tier-two triage across roughly 1,200 daily alerts, mapping adversary behavior to MITRE ATT&CK so escalations carry context instead of raw logs. When a phishing campaign slipped past our gateway and harvested three sets of credentials, I led the incident response: isolated the affected hosts, revoked the sessions, and closed containment in under 30 minutes with zero lateral movement. I documented the root cause and wrote the detection rule that has caught four similar attempts since.
Vulnerability management is the other half of my week. I prioritize remediation by exploitability and business impact rather than raw CVSS, which helped us clear 94 percent of critical findings within SLA last quarter, up from 70 percent. I hold Security+ and am partway through my CISSP, and I am comfortable scripting in Python to automate the repetitive parts of triage.
What draws me to [Company] is your move toward proactive threat hunting rather than reactive alerting. I would welcome the chance to help build detections that find quiet threats early. Thank you for considering my application.
Sincerely,
[Your Name]
