Its quite an interesting and a broad question. The answers you would receive would not be unique however it will be good to understand the view points.
Since you donot want a specific VPN products, I will try to answer in non-technical language.
1) Main point: amount of security needed for comunication?
Doesn't matter: Go for PPTP or L2TP
Must : IPSec or SSL
2) Will users be connecting while traveling/home i.e Remote Access solution ? or two company locations needs to communicate securely i.e. Site to Site ?
Remote Access: PPTP, L2TP, IPsec Client or SSL VPN
Site to Site: IPSec only !!!
less: PPTP or L2TP
good: IPSec or SSL. and if you need remote access, I would recommend SSL because your helpdesk would not get call for installing the IPSec Software, configuring it.In SSL VPN , all you need is your SSL compatible browser !
4) Choice between installing software vs browser based
Ok to install software of PC: IPsec
No ! I dont want any software or client : SSL
I dont want to install any software but if there is something in built ,I don't mind using it: PPTP, L2TP
5) Ease of configuring the VPN Gateways:
More of less equal ( cos you can find the configuration guides etc on internet ). IPSec with different OS can get into issues !
6) Number of users using VPN
less users: doesn't make business sense to invest in a vendor solution.So you would like to use something which would be inbuilt in windows. PPTP and L2TP can be used in such cases.
more users:If its a big rollout, you would definitely wanna go for either SSL or IPSec
7) Comparable Speed ( this is debatable, but below id my view).
IPSec is faster than SSL
Other factors could be: type of users ( techie or non-techie), ease of troubleshooting etc
Hope this helps. Please let me know if you have questions.
