Senior Security Analyst @ Fanatics

IT & Security (1)

Job Overview:

The Senior Cyber Security Analyst will play a key leadership role within the Perimeter Security team, focusing on network perimeter defense for our public web, api, and partner platforms . The Senior Analyst will be responsible for identifying and prioritizing edge threats, managing cybersecurity incidents, performing advanced threat hunting, and maintaining system integrations. The role requires collaboration with Security Engineering, Application Engineering, Site Reliability(SRE), and infrastructure teams to safeguard the organization's application perimeter, leveraging tools such as Splunk, native database queries, CDN defensive systems, WAFs, and internal security tools.

Key Responsibilities:
1. Incident Response & Mitigation:
○ Lead responses to traffic and perimeter-related security incidents, ensuring the
accurate identification and prioritization of edge threats.
○ Leverage CDN defenses, WAFs, and internal tooling to quickly implement
effective mitigations.
○ Focus on reducing false positive rates by refining detection and mitigation
techniques to ensure defensive systems have minimal operational impact while
maintaining robust security.
○ Detect, analyze, and investigate incidents involving customer traffic interference,
bot activity, scanners, and malicious actors.
○ Utilize native database queries, Splunk, and other monitoring platforms to identify
patterns and anomalies indicative of security risks.
○ Manage the prioritization and escalation of incidents based on severity, working
closely with Web Engineering, SRE, and infrastructure teams to drive rapid
mitigation.
2. Threat Monitoring, Hunting & False Positive Reduction:
○ Proactively monitor traffic patterns using Splunk, internal databases, and other
security tools to identify and assess threats within cloud environments.
○ Track and analyze threat actors, scanner activities, and IP reputation to
distinguish between legitimate threats and benign anomalies, with a strong
emphasis on reducing false positives.
○ Investigate traffic anomalies to proactively mitigate operational impacts on
engineering teams and ensure optimized security controls.
○ Collaborate closely with Web Engineering and SRE teams to minimize customer
impact and refine mitigation processes for greater accuracy.
3. System Integration & Maintenance:
○ Ensure seamless integration, patching, and ongoing maintenance of security
controls for cloud perimeter systems, including CDNs, WAFs, SigSci, and
NGINX.
○ Lead efforts to identify and address vulnerabilities related to API endpoints and
cloud services.

○ Maintain continuous monitoring of cloud-based perimeter security applications,
ensuring resilience against emerging threats.
4. Collaboration with Engineering and Operations Teams:
○ Partner with Security Engineering, Application Engineering, Web Engineering,
and SRE teams to embed security into new systems, endpoints, and integrations
from the start.
○ Lead cross-functional efforts to optimize security controls, reduce alert noise, and
minimize operational impacts while ensuring strong perimeter defenses.
○ Document, communicate, and prioritize security incidents, recommended actions,
and resolutions clearly to both technical and non-technical stakeholders.
5. Reporting & Documentation:
○ Generate and present executive-level reports on traffic mitigation, including
metrics such as sessions impacted by mitigation systems, financial savings from
bot/attack prevention, and availability impacts due to traffic anomalies.
○ Maintain comprehensive documentation on incidents, threat patterns, system
changes, and mitigation strategies to support continuous improvement.
○ Regularly report on efforts to reduce false positives and improve the operational
impact of mitigation technologies.

Qualifications
● Exceptional proficiency in the English language, both written and verbal, with a
demonstrated ability to craft detailed, engaging, and audience-appropriate reports for
peers and leadership.
● Strong analytical skills with a proven ability to quickly identify and mitigate complex
threats in high-volume environments.
● Bachelor’s degree in Cybersecurity, Computer Science, or a related field, or equivalent
work experience.
● Minimum of 6 years of experience in cybersecurity or public application software
engineering, with a focus on CDN Management, cloud technologies and perimeter
security.
● Extensive experience in incident response, cloud-native threat hunting, and mitigation in public/private/hybrid cloud environments (e.g., AWS, Azure, GCP).
● Strong hands-on experience with traffic and threat monitoring tools such as Splunk,
native database queries, and cloud-native security solutions.
● Deep knowledge of CDNs, WAFs, firewalls, IDS/IPS, and API security, particularly in
cloud-based architectures.
● Proficiency with web and API systems such as NGINX, Kubernetes, Apache, Web
Servers, along with cloud-native edge defense platforms.
