SaferVPN

SaferVPN is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SaferVPN rather than just read about it. In short: SaferVPN was a VPN service developed by Safer Social, Ltd. History SaferVPN was released in 2013 by Amit Bareket and Sagi Gidali.

Key takeaways

SaferVPN belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SaferVPN to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SaferVPN from memory before moving on to harder problems.

Reference excerpt

SaferVPN was a VPN service developed by Safer Social, Ltd.

History SaferVPN was released in 2013 by Amit Bareket and Sagi Gidali. SaferVPN network infrastructure served as the basis of Bareket's and Gidali's next company, Perimeter 81. The service was acquired by J2 Global in 2019 Q3 and was eventually merged into StrongVPN. On December 6, 2023 SaferVPN sent an email notifying customers of SaferVPN ending as on December 15, 2023.

Technology SaferVPN utilized the protocols OpenVPN, PPTP, L2TP and IKEv2.

Worked examples

Example 1 — a first encounter with SaferVPN

Start with the simplest possible case. Write down what SaferVPN claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SaferVPN before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SaferVPN ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SaferVPN

In research: SaferVPN appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses SaferVPN in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: SaferVPN is common in secondary-school and first-year university syllabi. It links to neighbouring topics Virtual private network services, so understanding it makes those chapters shorter.
In everyday life: Look for SaferVPN outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is SaferVPN in simple terms?

SaferVPN was a VPN service developed by Safer Social, Ltd. History SaferVPN was released in 2013 by Amit Bareket and Sagi Gidali.

Why does SaferVPN matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study SaferVPN?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
