Your Impact

• SaaS Security Posture Management (SSPM): Drive the rollout and ongoing management of the company’s SSPM program, identifying and remediating misconfigurations across SaaS applications. Triage and prioritize findings, translate them into actionable remediation plans, and work closely with application owners and IT to close gaps and track resolution.
• Endpoint Vulnerability Management: Own the endpoint vulnerability management lifecycle, from scanning and discovery through to prioritization, remediation tracking, and reporting. Collaborate with IT and infrastructure teams to ensure timely patching and configuration hardening across the endpoint estate, and provide risk-based guidance on outstanding vulnerabilities.
• Office & Corporate Network Security: Design, maintain, and continuously improve the security posture of office and corporate network environments. This includes firewall policy management, network segmentation, DNS security controls, wireless security, and monitoring for anomalous traffic or lateral movement within the corporate network.
• Email Security: Administer and optimize email security controls to protect the organization from phishing, spoofing, malware delivery, and business email compromise. Maintain and tune anti-spam, anti-phishing, and sandboxing configurations, and ensure strong enforcement of SPF, DKIM, and DMARC policies.
• DNS & Web Security: Manage DNS security controls including protective DNS filtering and response policy zones to block malicious domains and prevent data exfiltration. Administer web security gateways and content filtering solutions to enforce acceptable use policies and protect users from web-based threats, both on-network and when roaming.
• Security Tooling Administration: Take ownership of the day-to-day administration of enterprise security platforms, including configuration management, policy tuning, license management, and vendor engagement. Ensure tooling is operating effectively, alert fidelity is maintained, and platforms are integrated to provide clear visibility across the enterprise environment.
• Cross-Functional Collaboration: Act as a key security partner to IT, infrastructure, and enterprise technology teams, providing security guidance on new tooling deployments, system changes, and technology projects. Contribute to the broader security program by supporting risk assessments, policy development, and security awareness initiatives relevant to enterprise systems.

• Enterprise Security Experience: Demonstrable experience working within an enterprise or corporate security function, with hands-on responsibility for protecting corporate systems, endpoints, and networks. A solid understanding of the threat landscape facing enterprise environments and the controls used to manage risk at scale.
• SSPM & SaaS Security: Practical experience with SaaS Security Posture Management tooling (e.g., Adaptive Shield, AppOmni, Obsidian Security, or Microsoft Defender for Cloud Apps) and a strong understanding of common SaaS misconfiguration risks. Ability to communicate findings clearly and drive remediation across business and technical stakeholders.
• Endpoint Vulnerability Management: Hands-on experience with vulnerability scanning and management platforms such as Qualys, Tenable, or Rapid7. Familiarity with vulnerability prioritization frameworks (e.g., CVSS, EPSS, CISA KEV) and the ability to work with IT teams to drive timely and effective remediation.
• Email Security: Deep technical knowledge of email security controls, including SPF, DKIM, and DMARC configuration and enforcement, and experience administering enterprise email security platforms such as Proofpoint, Mimecast, or Microsoft Defender for Office 365. Ability to investigate and respond to email-based threats and phishing incidents.
• DNS & Web Security: Experience deploying and managing protective DNS solutions (e.g., Cisco Umbrella, Infoblox BloxOne, Cloudflare Gateway) and web security gateways or proxies (e.g., Zscaler, Netskope, Symantec Web Security Service). Understanding of DNS-based attack techniques and how to detect and block them.
• Network Security: Working knowledge of corporate network security principles, including firewall policy management, IDS/IPS, network segmentation and micro-segmentation, NAC, and Wi-Fi security. Experience with enterprise network security vendors such as Palo Alto Networks, Fortinet, or Cisco is beneficial.
• Security Tooling Administration: Proven ability to administer, tune, and maintain security platforms in a production enterprise environment. Comfort with configuring integrations between tools, managing alert workflows, and driving value from security investments through active, hands-on ownership.
• Security Frameworks & Standards: Familiarity with relevant security frameworks and standards such as NIST CSF, CIS Benchmarks, and ISO 27001, and an understanding of how enterprise security controls map to compliance and audit requirements.
