8. Social media links in the footer.
9. Personalized information for Gourav Gour, including his name, contact details, and a brief introduction.

Remember to replace any placeholder content with Gourav's actual projects, certifications, and other relevant information. Also, ensure that all information shared complies with any non-disclosure agreements and ethical guidelines in the cybersecurity field.
