Website has no security certificate
Yes, currently the website has no security certificate as we had to reissue due to sub-domain issues. We are currently waiting for the SSL Certificate to propagate. (Could be anywhere between 12hr - 48hrs)
Mainnet wallets are not available for obvious reasons. Firstly, we are still a week away from mainnet launch and we won't be hashing the genesis block until a day prior to launch, hence no use for wallet until that day. Secondly, if wallets are released for download now, and include the genesis block (1 week prior to launch) there would be opportunity to solo mine/wallet mine before the scheduled launch.
However, If you feel you must see a wallet, feel free to download the testnet version, which is still available on github.
I hope this has cleared up your questions
