توفر الشبكة الخاصة الافتراضية اتصالاً خاصاً بين الأجهزة على الإنترنت، وتستخدم لأغراض الأمان في نقل البيانات مع إخفاء الهوية الشخصية على الشبكة العامة، إضافة لتغيير عناوين بروتوكولات الإنترنت وتشفير البيانات بحيث لا يستطيع قراءتها إلا الشخص نفسه.
تعتبر هذه الشبكات مهمة للغاية لعدة أسباب ومنها:
يعمل اتصال الشبكة الخاصة الافتراضية على إعادة توجيه حزم البيانات من جهاز المستخدم إلى خادم افتراضي بعيد قبل إرسالها إلى الوجهة المطلوبة وفق مرحلتين أساسيتين وهما:
يوجد نوعان أساسيان من الشبكات الخاصة الافتراضية المتمايزة وهي:
