Private equity firm LLR Partners has made an investment in IJet International Inc.

Annapolis, Md.-based IJet delivers intelligence, preparedness and response services to more than 600 corporations and government organizations to help them try to mitigate risks that could affect operational performance.

LLR’s investment should allow IJet to expand its customer base, expand relationships, invest in technology and pursue strategic acquisitions.

Philadelphia-based LLR invests in a variety of middle-market businesses, including those in the consumer goods, education, financial services, government services, health care, software and information technology sectors. The firm has about $2.4 billion in capital commitments. In October, LLR teamed with Updata Partners and invested $27.5 million investment in Logi Analytics, a data analysis company.
