The Russian-American Company was founded under the auspices of the Tsar. Hence, it was not really a "private" company, but what we Americans would call a government sponsored entity (GSE). Think "Fannie Mae" or "Freddie Mac." In fact, the original founding merchants were soon displaced as shareholders by nobles and aristocrats, particularly government officials.
Thus, an employee of the company had two allegiances; to the company itself, and to the Russian government. While "salaried agents" were representatives of the former, the Commandant of Okhotsk was a "local" representative of the latter. He may have overstepped his bounds by demanding that the employees pledge allegiance to him personally, but basically, he was doing his job by "overseeing" the Russian-American Company and its employees.
As this note to Fort Ross (California) explains, the Russian government sent soldiers to protect what were technically commercial, rather than military, ventures in its far-flung "outpost" regions. From the Wikipedia article:
"Between twelve and forty cannons were placed within the stockade and blockhouses, the number varying in the different accounts of the site written over the years. Sentries bearing flintlock muskets stood guard in each blockhouse, but although it was fortified, the settlement served as a commercial, not a military outpost. Flagstaffs were first erected in the center of the stockade and outside it on the bluff, each bearing the flag of the Russian-American Company, with the imperial double-headed eagle as its insignia."
A reason may have been that they could not have been protected by conventional diplomatic means, given the power vacuums that existed in these remote areas. Another reason was that the Russian-American Company was given the task of exploring and colonizing the lands that it was developing economically.
