About this course
Protocols make sense once you watch them happen, and that is what this course does. Inside an isolated lab you own, you use command-line capture tools to record and dissect real traffic rather than reading diagrams. You see how data is wrapped in layers, how TCP negotiates a connection with SYN, SYN-ACK and ACK, and why UDP's lack of a handshake makes spoofing easy. You explore how DNS resolves names and where it gets abused, why plaintext HTTP exposes everything while TLS seals the content, and how ARP and ICMP move packets on the local segment. A lesson on the OSI model ties the vocabulary together, followed by NAT, routing and VPN concepts. A capstone has you fingerprint a host from its packets alone. Quizzes and a final exam lead to a certificate.

Questions about this course
Is this a subscription?
No. You pay $9.99 once for this course. There is no subscription and nothing renews automatically. Prices are in US dollars; taxes may be added where required.
What exactly do I get?
All lessons and labs of this course, the final exam and the certificate, including later updates to the course, for as long as Tutorvo offers it. Access is personal and tied to your account.
Can I get a refund?
Yes. If you are not satisfied, email hello@tutorvo.com within 14 days of buying and we refund the course in full via Stripe. The guarantee does not apply once a certificate for the course has been issued to you, or where there are signs of abuse.
When can I start?
Right after payment. Access starts immediately at your request; for consumers in the EU/EEA the statutory right of withdrawal therefore ends once access has begun, while our 14-day money-back guarantee applies regardless.
Do I need Excel or other software?
No. The labs run in a spreadsheet inside your browser on a laptop, tablet or phone. Function names and syntax follow Excel.
Is the certificate an official qualification?
No. It confirms that you completed all lessons of the course and passed its final exam. It is not an official, state-recognised or professional qualification. The name is taken from your profile when the certificate is issued.
