Natan Jeferli

• Played a key role in making engineered solutions standardized and well-documented for customers. This led to better efficiency and safer solutions for them.
• Implemented IPsec RA, SSL VPN, and centralized 2FA for endpoints. Also set up SAML, FortiToken, and other MFA tools as needed by our clients.
• Implemented FortiManager for the provisioning of FortiGates. After they were provisioned, FortiManager was used for managing all subsequent changes and for revision control.
• I've set up FortiAnalyzer for centralized log management across all FortiGates within our customer's environments. This setup enabled the creation of event and incident handlers, as well as reports, tailored to each customer's specific needs. As a result, we've seen an improvement in security operations and efficiency, along with a reduction in operational risks.
