Regular readers of The SSL Blog know that Extended Validation SSL has seen strong early uptake in the online investing space, as evidenced by early deployments by Charles Schwab and E*TRADE. Now you can add Scottrade to the mix.
Why so much interest among online investing sites? It makes perfect sense to me. These sites have high value customers that they want to retain, and they manage a high value financial asset that the customer considers important to keep safe. Their customers are juicy identity theft targets since they tend to have money and good credit. And of course the presence of pump and dump scams make these sites into major phishing targets.
