I find the vulnerabilities in your web apps, APIs, and networks before attackers do, then hand your team a clear, reproducible penetration testing report they can act on. GXPN and GCIH certified. Top Rated on Upwork with 100% Job Success across web application, API, and network security engagements. No scanner dump and no jargon wall. Every finding comes with a severity rating (CVSS), working proof of concept, and a concrete fix your developers can ship. What I test: - Web application penetration testing (OWASP Top 10, PTES, NIST) - API security testing (REST, GraphQL, auth/OAuth, IDOR, broken access control) - SaaS and multi-tenant assessments (Supabase / Firebase data-isolation testing) - Network and external perimeter penetration testing - Source code / secure code review How I work: authorized testing only, on systems you own or have permission to test. Everything is documented over Upwork so you get a written record of every finding, not a verbal hand-wave. I retest after you patch to confirm the holes are actually closed. Credentials: GXPN (GIAC Advanced Penetration Tester & Exploit Researcher), GCIH (GIAC Certified Incident Handler), SANS CTF winner, and an active national/international CTF competitor (web, reverse, crypto, forensics). I also handle WordPress malware removal and incident response. See my Project Catalog for a fixed-price option.

What does an Antispam and Antivirus specialist do?

An Antispam and Antivirus specialist configures email security gateways to block spam, viruses, and malware before they reach user inboxes. This role focuses on tuning detection policies and managing quarantine workflows to maintain secure communication channels without disrupting legitimate business correspondence. You analyze message logs and threat reports to identify false positives and adjust filtering rules accordingly.

  • Configure antispam and antivirus scanning behavior for inbound email processing by defining specific filter actions such as deliver, drop, quarantine, or notify. You set up message routing rules within the email security gateway to enforce these policies consistently across the organization.
  • Tune security settings including URL handling, sandboxing, and exception lists to reduce risk while minimizing false positives. This work involves reviewing detection outcomes from message logs and reports to refine filters and ensure legitimate emails pass through without unnecessary delays.
  • Integrate email security logging with a Security Information and Event Management (SIEM) system for continuous monitoring and alerting. You investigate spam and malware detections by analyzing log-based findings and coordinate security incidents using integrated investigation views to resolve threats quickly.

How to hire an Antispam and Antivirus specialist on Upwork

Step 1: Post a job

Define your email security needs clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description in seconds. Describe your requirements in a few sentences, and Uma creates a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing one.

  • Specify the email security gateway or secure email platform you use so candidates confirm compatibility with your infrastructure.
  • List required policy management tasks, such as configuring filter actions like quarantine, drop, or notify for detected threats.
  • Mention integration needs, such as connecting email security logs to your SIEM for centralized monitoring and alerting.

Step 2: Evaluate candidates

Look for proof of hands-on experience with email threat detection and policy tuning. Uma runs instant video interviews and builds shortlists with side-by-side comparisons to speed up your review. Focus on candidates who show measurable improvements in false positive reduction or threat capture rates.

  • Review portfolio items that document specific tuning changes, such as adjusted exceptions or URL handling rules that reduced risk.
  • Check for investigation outputs, such as log-based findings from spam or malware detections that led to resolved security incidents.
  • Verify experience with operational reports that track message security activity and filter outcomes over time.

Step 3: Interview your top choices

Discuss technical approaches to balancing security strictness with email deliverability. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session. Ask about their process for validating filter effectiveness without blocking legitimate business communication.

  • Ask how they configure quarantines or notification behaviors to keep users informed about blocked messages.
  • Request examples of how they triage issues using message logs and dashboards to validate scanning effectiveness.
  • Discuss their method for coordinating security incidents using integrated logging and investigation views.

Step 4: Agree on scope and begin work

Set clear milestones for policy configuration, testing, and documentation. Use Upwork Messages and the contract workroom for all communication and project management. Upwork verifies identity, offers Hourly Payment Protection, tracks hours, and holds project funds for security.

  • Define deliverables such as configured antispam and antivirus policies with documented filter actions for email processing.
  • Require documentation of security settings, including routing rules, scanning parameters, and quarantine behaviors.
  • Set a milestone for submitting tuning changes and verification results that confirm adjusted filters work as intended.
