Who is Jan Krislov from Mortal Fear and what is their importance?

Jan is the widow who owns EROS. Jan is known for her outspoken views on several topics, including privacy. With that in mind, it's no wonder that she's serious about protecting the privacy of those who use EROS. She provides several safeguards, billing is done automatically and there is a monetary compensation if the membership information of anyone becomes generally known. This makes Harper's actions more serious because he's violated his company's policy.
